A table's filenode often matches its OID, this is not necessarily the case. If table names contain any characters except letters, numbers, and underscores, the name must be delimited by enclosing it in back quotes (`). pg_hba.conf file is checked from the top down, for each connection request. We can check that by firing the following query. This is somewhat hokey but could be a contender if you are looking for the shortest possible SQL: SELECT json_object_keys(to_json(json_populate_record(NULL::schema_name.table_name, '{}'::JSON))) or even shorter (assuming there is at least one row present in the table) Every table has a name, every column has a name, and so on.

Roles must pass requirements from both the pg_hba.conf file and database level access privileges. This arrangement avoids problems on platforms that have file size limitations. If you are installing PostgreSQL into a Windows system that is configured with User Account Control (UAC) enabled, you can assume sufficient privileges to invoke the graphical installer by right clicking on the name of the installer and selecting Run as administrator from the context menu. The column names are also configuration, see the inline documentation for examples. The first segment's file name is the same as the filenode; subsequent segments are named filenode.1, filenode.2, etc. If prompted, enter an administrator password to continue.
