# PostgreSQL User Name Maps # ========================= # # Refer to the PostgreSQL documentation, chapter "Client # Authentication" for a complete description. A short synopsis # follows. # # This file controls PostgreSQL user name mapping. It maps external # user names to their corresponding PostgreSQL user names. Records # are of the form: # # MAPNAME SYSTEM-USERNAME PG-USERNAME # # (The uppercase quantities must be replaced by actual values.) # # MAPNAME is the (otherwise freely chosen) map name that was used in # pg_hba.conf. SYSTEM-USERNAME is the detected user name of the # client. PG-USERNAME is the requested PostgreSQL user name. The # existence of a record specifies that SYSTEM-USERNAME may connect as # PG-USERNAME. # # If SYSTEM-USERNAME starts with a slash (/), it will be treated as a # regular expression. Optionally this can contain a capture (a # parenthesized subexpression). The substring matching the capture # will be substituted for \1 (backslash-one) if present in # PG-USERNAME. # # Multiple maps may be specified in this file and used by pg_hba.conf. # # No map names are defined in the default configuration. If all # system user names and PostgreSQL user names are the same, you don't # need anything in this file. # # This file is read on server startup and when the postmaster receives # a SIGHUP signal. If you edit the file on a running system, you have # to SIGHUP the postmaster for the changes to take effect. You can # use "pg_ctl reload" to do that. # Put your actual configuration here # ---------------------------------- # MAPNAME SYSTEM-USERNAME PG-USERNAME
