Subject: Unbreak legacy syntax "COMMENT ON RULE x IS y", with no relation name.
X-Git-Tag: REL9_1_RC1~30
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a60c16db5f36562df571d36fcacbbed33fd40bd4;p=postgresql

Unbreak legacy syntax "COMMENT ON RULE x IS y", with no relation name.

check_object_ownership() isn't happy about the null relation pointer.
We could fix it there, but this seems more future-proof.
