Subject: Document permissions needed for pg_database_size and pg_tablespace_size.
X-Git-Tag: REL8_4_22~31
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=519c32fa004712888347115fbb493d31315a17a1;p=thirdparty%2Fpostgresql.git

Document permissions needed for pg_database_size and pg_tablespace_size.

Back in 8.3, we installed permissions checks in these functions (see
commits 8bc225e7990a and cc26599b7206).  But we forgot to document that
anywhere in the user-facing docs; it did get mentioned in the 8.3 release
notes, but nobody's looking at that any more.  Per gripe from Suya Huang.
