Subject: Show schemas in information_schema.schemata that the current has access to
X-Git-Tag: REL9_4_BETA1~1157
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b34f8f409bec4921d260ac84668917f5fff04319;p=postgresql

Show schemas in information_schema.schemata that the current has access to

Before, it would only show schemas that the current user owns.  Per
discussion, the new behavior is more useful and consistent for PostgreSQL.
