commit b3ce55f413cdf70b1bc4724052fb4eacf9de239a
Author: Nathan Bossart <nathan@postgresql.org>
Date: Tue Oct 28 19:08:38 2025 +0000
Add psql PROMPT variable for search_path.
The new %S substitution shows the current value of search_path.
Note that this only works when connected to Postgres v18 or newer,
since search_path was first marked as GUC_REPORT in commit
28a1121fd9. On older versions that don't report search_path, %S is
replaced with a question mark.
