While the latter behavior is clearly a bug, there might be applications depending on the former behavior; therefore the function declarations will not be changed by default until PostgreSQL 9.5. In pre-9.5 branches, the old behavior exists in version 1.0 of the citext extension, while we have provided corrected declarations in version 1.1 (which is not installed by default). To adopt the fix in pre-9.5 branches, execute ALTER EXTENSION citext UPDATE TO '1.1' in each database in which citext is installed. (You can also update back to 1.0 if you need to undo that.) Be aware that either update direction will require dropping and recreating any views or rules that use citext's regexp_matches() functions.", "commit_aliases": [], "source_commits": [], "source_entry_id": "9.3.7/changes/005", "db_id": "0dd364915620bdc5a624315bc36c8273", "patch_ids": [], "statement_hash": "116f9549ad994e5ad9ffab4ed649d61c605912cec1d818a5b83b4d055097cf61", "relations": [{"rule": 2, "type": "equivalent", "target": "24b89adf3b27f5daabdffe0a9be1a23e", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "116f9549ad994e5ad9ffab4ed649d61c605912cec1d818a5b83b4d055097cf61"}}, {"rule": 2, "type": "equivalent", "target": "94f52f1c4c1ad587b8738bf0394bc81b", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "116f9549ad994e5ad9ffab4ed649d61c605912cec1d818a5b83b4d055097cf61"}}, {"rule": 2, "type": "equivalent", "target": "c50b7a9a12142eb6cb274f3cbb9b2ef9", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "116f9549ad994e5ad9ffab4ed649d61c605912cec1d818a5b83b4d055097cf61"}}], "version": "9.3.7", "category_label": "Bug fixes", "also_in": [], "variants": [], "related_changes": [{"db_id": "24b89adf3b27f5daabdffe0a9be1a23e", "kind": "equivalent", "version": "9.4.2", "label": "9.4.2", "title": "Fix incorrect declaration of contrib/citext's regexp_matches() functions", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "116f9549ad994e5ad9ffab4ed649d61c605912cec1d818a5b83b4d055097cf61"}, "url": "/docs/compare/?release=9.4.2#9.4.2-225393d2bd00cdb6", "source_url": "/docs/release/9.4.2/#AEN123323"}, {"db_id": "c50b7a9a12142eb6cb274f3cbb9b2ef9", "kind": "equivalent", "version": "9.2.11", "label": "9.2.11", "title": "Fix incorrect declaration of contrib/citext's regexp_matches() functions", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "116f9549ad994e5ad9ffab4ed649d61c605912cec1d818a5b83b4d055097cf61"}, "url": "/docs/compare/?release=9.2.11#9.2.11-225393d2bd00cdb6", "source_url": "/docs/release/9.2.11/#AEN112334"}, {"db_id": "94f52f1c4c1ad587b8738bf0394bc81b", "kind": "equivalent", "version": "9.1.16", "label": "9.1.16", "title": "Fix incorrect declaration of contrib/citext's regexp_matches() functions", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "116f9549ad994e5ad9ffab4ed649d61c605912cec1d818a5b83b4d055097cf61"}, "url": "/docs/compare/?release=9.1.16#9.1.16-225393d2bd00cdb6", "source_url": "/docs/release/9.1.16/#AEN107832"}]}, {"id": "9.3.7-ee55477e69926c73", "cves": [], "html": "Fix incorrect checking of deferred exclusion constraints after a HOT update (Tom Lane)

\nA numeric value's display scale (dscale) should never be less than the number of nonzero fractional digits; but apparently there's at least one broken client application that transmits binary numeric values in which that's true.

In such timezones, PostgreSQL will now associate the correct UTC offset with the abbreviation depending on the given date.", "commit_aliases": ["137e7c164", "2784b68b3", "7c67b9365", "870a980aa"], "source_commits": ["137e7c164"], "source_entry_id": "9.3.6/changes/088", "db_id": "854ddf984dcdb9921b26d5ae0ee9de60", "patch_ids": ["ad15ff2e7457fbbc410de3eea2dff439"], "statement_hash": "a6501e3be8faaec1aef9006ff3436c99d826569caaba0e379a16ca0000209bff", "relations": [{"rule": 2, "type": "equivalent", "target": "9231b02c97705c0ca64095e3e093c6de", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "a6501e3be8faaec1aef9006ff3436c99d826569caaba0e379a16ca0000209bff"}}, {"rule": 2, "type": "equivalent", "target": "b4cdc7057684904bbb5e7ccbfa582405", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "a6501e3be8faaec1aef9006ff3436c99d826569caaba0e379a16ca0000209bff"}}, {"rule": 2, "type": "equivalent", "target": "f08e49dc6b542196f8383acd3b0b9c65", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "a6501e3be8faaec1aef9006ff3436c99d826569caaba0e379a16ca0000209bff"}}], "version": "9.3.6", "category_label": "Improvements", "also_in": [], "variants": [], "related_changes": [{"db_id": "9231b02c97705c0ca64095e3e093c6de", "kind": "equivalent", "version": "9.2.10", "label": "9.2.10", "title": "Support time zone abbreviations that change UTC offset from time to time", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "a6501e3be8faaec1aef9006ff3436c99d826569caaba0e379a16ca0000209bff"}, "url": "/docs/compare/?release=9.2.10#9.2.10-e7903bd697407838", "source_url": "/docs/release/9.2.10/#AEN112547"}, {"db_id": "f08e49dc6b542196f8383acd3b0b9c65", "kind": "equivalent", "version": "9.1.15", "label": "9.1.15", "title": "Support time zone abbreviations that change UTC offset from time to time", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "a6501e3be8faaec1aef9006ff3436c99d826569caaba0e379a16ca0000209bff"}, "url": "/docs/compare/?release=9.1.15#9.1.15-e7903bd697407838", "source_url": "/docs/release/9.1.15/#AEN108024"}, {"db_id": "b4cdc7057684904bbb5e7ccbfa582405", "kind": "equivalent", "version": "9.0.19", "label": "9.0.19", "title": "Support time zone abbreviations that change UTC offset from time to time", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "a6501e3be8faaec1aef9006ff3436c99d826569caaba0e379a16ca0000209bff"}, "url": "/docs/compare/?release=9.0.19#9.0.19-e7903bd697407838", "source_url": "/docs/release/9.0.19/#AEN99745"}]}, {"id": "9.3.6-1ddb498d1e51e878", "cves": [], "html": "Update time zone abbreviations lists (Tom Lane)

\nHowever, several of the issues corrected in this release could have resulted in corruption of foreign-key constraints; that is, there might now be referencing rows for which there is no matching row in the referenced table. It may be worthwhile to recheck such constraints after installing this update. The simplest way to do that is to drop and recreate each suspect constraint; however, that will require taking an exclusive lock on both tables, so it is unlikely to be acceptable in production databases. Alternatively, you can do a manual join query between the two tables to look for unmatched rows.
\nNote also the requirement for replication standby servers to be upgraded before their master server is upgraded.
\nAlso, if you are upgrading from a version earlier than 9.3.2, see Section E.24.

\nIn some cases VACUUM (either manual or autovacuum) could incorrectly advance a table's relfrozenxid value, allowing tuples to escape freezing, causing those rows to become invisible once 2^31 transactions have elapsed. The probability of data loss is fairly low since multiple incorrect advancements would need to happen before actual loss occurs, but it's not zero.
