Thread: psql profiles?

psql profiles?

From
Matt Zagrabelny

Greetings,

I'm setting up my workstation to use "gss" for auth to a variety of Pg systems on different hosts.

I'd rather not have to specify the "-h" for a connection:


I'd rather do:

psql foo

and have it know that I connect to foo on host db-host-1.example.com.

Is this possible with psql or do I hack together some wrapper script?

Thanks for any input!

Sure, just define a pg_service.conf file.

Thanks Alvaro!

Is there any shorter version than:

psql "service=foo"

?

If not, I can make a shell alias that puts the "service=$@" into the command.

Thanks again!

Also you can set environment variable PGSERVICE=foo in your .bashrc. Or 
you can just set variable PGHOST=db-host-1.example.com. In last case you 
don't need pg_service.conf file.

Thanks for the hints and discussion about this.

Here's my final implementation for the curious and to close the loop:

# a zsh function to avoid having to type "service="

$ which pssql
pssql () {
        psql "service=$@"
}

# and a zsh completion function:

$ cat ~/.fpath/_pssql
#compdef pssql

PG_SERVICES_CONF=~/.pg_service.conf

if [[ -r ${PG_SERVICES_CONF} ]]; then
    compadd $(sed -nE 's/^ *\[(.*)\] *$/\1/p' ${PG_SERVICES_CONF})
fi

 It works like a charm!

Thanks for all the help!

I made bash functions to do something similar, with just hardcoded server names.  It has auto-complete and allows me to use descriptive names instead of server names and custom postgres versions.
