表 45.27. pg_language 列
| Name | Type | References | Description |
|---|---|---|---|
lanname | name | Name of the language | |
lanowner | oid | | Owner of the language |
lanispl | bool | This is false for internal languages (such as SQL) and true for user-defined languages. Currently, pg_dump still uses this to determine which languages need to be dumped, but this might be replaced by a different mechanism in the future. | |
lanpltrusted | bool | True if this is a trusted language, which means that it is believed not to grant access to anything outside the normal SQL execution environment. Only superusers can create functions in untrusted languages. | |
lanplcallfoid | oid | | For noninternal languages this references the language handler, which is a special function that is responsible for executing all functions that are written in the particular language |
laninline | oid | | This references a function that is responsible for executing “inline” anonymous code blocks (DO blocks). Zero if inline blocks are not supported. |
lanvalidator | oid | | This references a language validator function that is responsible for checking the syntax and validity of new functions when they are created. Zero if no validator is provided. |
lanacl | aclitem[] | Access privileges; see GRANT and REVOKE for details |
