# 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
