Fix incorrect compression logic for GIN posting lists (Heikki Linnakangas)
\nA GIN posting list item can require 7 bytes if the distance between adjacent indexed TIDs exceeds 16TB. One step in the logic was out of sync with that, and might try to write the value into a 6-byte buffer. In principle this could cause a stack overrun, but on most architectures it's likely that the next byte would be unused alignment padding, making the bug harmless. In any case the bug would be very difficult to hit.

This risk was created by a misplaced declaration: ecpg_gettext() should not be visible to client code.
In psql, resynchronize internal state about the server after an unexpected connection loss and successful reconnection (Peter Billen, Tom Lane)
\nOrdinarily this is unnecessary since the state would be the same anyway. But it can matter in corner cases, such as where the connection might lead to one of several servers. This change causes psql to re-issue any interactive messages that it would have issued at startup, for example about whether SSL is in use.

In pg_restore, treat -f - as meaning “output to stdout” (Álvaro Herrera)
This synchronizes pg_restore's behavior with some other applications, and in particular makes pre-v12 branches act similarly to version 12's pg_restore, simplifying creation of dump/restore scripts that work across multiple PostgreSQL versions. Before this change, pg_restore interpreted such a switch as meaning “output to a file named -”, but few people would want that.
