Subject: Fix pg_hba_file_rules for authentication method cert
X-Git-Tag: REL_13_6~15
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=81596645ca2ba382918fca9e82aa3089db737e14;p=thirdparty%2Fpostgresql.git

Fix pg_hba_file_rules for authentication method cert

For authentication method cert, clientcert=verify-full is implied. But
the pg_hba_file_rules entry would incorrectly show clientcert=verify-ca.

Per bug #17354
