[COMMITTERS] pgsql: Move autogenerated array types out of the way during ALTER ...R - Mailing list pgsql-committers

Move autogenerated array types out of the way during ALTER ... RENAME.

Commit 9aa3c782c added code to allow CREATE TABLE/CREATE TYPE to not fail
when the desired type name conflicts with an autogenerated array type, by
dint of renaming the array type out of the way.  But I (tgl) overlooked
that the same case arises in ALTER TABLE/TYPE RENAME.  Fix that too.
Back-patch to all supported branches.
