Subject: pgsql: Always check foreign-server USAGE when resolving subscription co
Date: Wed, 05 Aug 2026 20:26:27 +0000
Message-ID: <E1wriC3-00000000LG8-3cb9@gemulon.postgresql.org> (raw)
Always check foreign-server USAGE when resolving subscription conninfo.
Previously, this was skipped in some cases to avoid raising errors
when conninfo wasn't even needed. That was wrong in cases where
conninfo was needed.
Now that we only build conninfo when needed, always perform the USAGE
check.
