Re: prevent immature WAL streaming - Mailing list pgsql-hackers

BTW while going about testing this, I noticed that we forbid
pg_walfile_name() while in recovery.  That restriction was added by
commit 370f770c15a4 because ThisTimeLineID was not set correctly during
recovery.  That was supposed to be fixed by commit 1148e22a82ed, so I
thought that it should be possible to remove the restriction.  However,
I did that per the attached patch, but was quickly disappointed because
ThisTimeLineID seems to remain zero in a standby for reasons that I
didn't investigate.
