=head1 NAME
pg_conftool - read and edit PostgreSQL cluster configuration files
=head1 SYNOPSIS
B<pg_conftool> [I<options>] [I<version> I<cluster>] [I<configfile>] B<command>
=head1 DESCRIPTION
B<pg_conftool> allows to show and set parameters in PostgreSQL configuration
files.
If I<version> I<cluster> is omitted, it defaults to the default cluster (see
user_clusters(5) and postgresqlrc(5)). If I<configfile> is omitted, it defaults
to B<postgresql.conf>. I<configfile> can also be a path, in which case
I<version> I<cluster> is ignored.
=head1 OPTIONS
=over 4
=item B<-s>, B<--short>
Show only the value (instead of key = value pair).
=item B<-v>, B<--verbose>
Verbose output.
=item B<--help>
Print help.
=back
=head1 COMMANDS
=over 4
=item B<show> I<parameter>|B<all>
Show a parameter, or all present in this config file.
=item B<set> I<parameter> I<value>
Set or update a parameter.
=item B<remove> I<parameter>
Remove (comment out) a parameter from a config file.
=item B<edit>
Open the config file in an editor. Unless B<$EDITOR> is set, B<vi> is used.
