[COMMITTERS] pgsql: Ignore CatalogSnapshot when checking COPY FREEZE prerequisites. - Mailing list pgsql-committers

Ignore CatalogSnapshot when checking COPY FREEZE prerequisites.

This restores the ability, essentially lost in commit
ffaa44cb559db332baeee7d25dedd74a61974203, to use COPY FREEZE under
REPEATABLE READ isolation.  Back-patch to 9.4, like that commit.

Reviewed by Tom Lane.
