Subject: pgsql: Fix some memory leaks in the WAL receiver

Message-ID: <E1wHAqa-002zLz-32@gemulon.postgresql.org> (raw)
Fix some memory leaks in the WAL receiver
These are old leaks, that can pile up if a WAL receiver stays alive,
waiting for new WAL data after the sender has switched to a new
timeline.
While this is technically a bug, the impact is minimal and would only
become noticeable if the WAL sender handles a lot of timeline switches,
so no backpatch is done. Note that in most cases, primary_conninfo
would be updated in a standby to point to a new sender, meaning a
restart of the WAL receiver. Let's be clean on HEAD, though.
