NAME Pg::ServiceFile - Basic PostgreSQL connection service file interface SYNOPSIS use Pg::ServiceFile; # Uses $ENV{PGSERVICEFILE} or user's `~/.pg_service.conf` file my $pgservice = Pg::ServiceFile->new(); # Use a specific service file - `pg_config --sysconfdir`/pg_service.conf my $pgservice = Pg::ServiceFile->new(file => '/etc/postgresql-common/pg_service.conf'); # Print all the service names say $_ for @{$pgservice->names}; # Get the username for a specific service name say $pgservice->services->{foo}->{user}; DESCRIPTION Pg::ServiceFile is a partially complete interface to the PostgreSQL connection service file. It's complete in the fact that it reads the $ENV{PGSERVICEFILE} or user service file as standard, but will not automatically retrieve and merge the system-wide service file or check PGSYSCONFDIR. If you know the connection service file you want to use, and just want the data as a HASH reference, you can use the simpler module Config::Pg::ServiceFile which has less dependencies and features. ATTRIBUTES Pg::ServiceFile implements the following attributes. data my $pgservice = Pg::ServiceFile->new(data => <<~'PGSERVICEFILE'); [foo] host=localhost port=5432 user=foo dbname=db_foo password=password PGSERVICEFILE my $pgservice = Pg::ServiceFile->new(file => '~/.pg_service.conf'); say $pgservice->data; The connection service file data. This is the contents of "file", or the data that has been passed in directly during instantiation. file my $pgservice = Pg::ServiceFile->new(); say $pgservice->file; # ~/.pg_service.conf (if it exists) my $pgservice = Pg::ServiceFile->new(file => '~/myservice.conf'); say $pgservice->file; # ~/myservice.conf Defaults to $ENV{PGSERVICEFILE} or ~/.pg_service.conf, but can be any valid connection service file. name local $ENV{PGSERVICE} = 'foo'; my $pgservice = Pg::ServiceFile->new(); say $pgservice->name; # foo say $pgservice->service->{dbname}; # db_foo The value of $ENV{PGSERVICE} if it exists, or whatever is set during instantiation. It does not check to see if a corresponding service entry exists in the service "file", but "service" will return the relevant data if it does. names my $pgservice = Pg::ServiceFile->new(); say $_ for @{$pgservice->names}; Returns the names of all the connection services from the service "file". service my $pgservice = Pg::ServiceFile->new(name => 'foo'); say $pgservice->service->{dbname}; # db_foo If "name" has been set via $ENV{PGSERVICE} or on instantiation, returns the corresponding connection service. See "name". services my $pgservice = Pg::ServiceFile->new(); while (my ($name, $service) = each %{$pgservice->services}) { say "[$name] $service->{dbname} at $service->{host}"; } Returns a HASH of all of the connection services from "file".
