Hi, Thanks for the patch.

This part of the documentation is wrong: ``` + <row> + <entry role="catalog_table_entry"><para role="column_definition"> + <structfield>authname</structfield> <type>name</type> + </para> ``` Actually the type is `text`: ``` =# \d pg_stat_activity ; View "pg_catalog.pg_stat_activity" Column | Type | Collation | Nullable | Default ------------------+--------------------------+-----------+----------+--------- datid | oid | | | datname | name | | | pid | integer | | | leader_pid | integer | | | usesysid | oid | | | usename | name | | | authname | text | | | ``` It hurts my sense of beauty that usename and authname are of different types. But if I'm the only one, maybe we can close our eyes on this. Also I suspect that placing usename and authname in a close proximity can be somewhat confusing. Perhaps adding authname as the last column of the view will solve both nitpicks? ``` + /* Information about the authenticated user */ + char st_authuser[NAMEDATALEN]; ``` Well, here it's called "authuser" and it looks like the intention was to use `name` datatype... I suggest using "authname" everywhere for consistency. Since the patch affects pg_proc.dat I believe the commit message should remind bumping the catalog version. -- Best regards, Aleksander Alekseev
