[check_postgres] recent commits break some thingS

[Cédric Villemain]

Hello,

I notice that some outputs got some bugs. I am using the git version 
(3c29a894837f484d9a0a4b7fb61c4676eeb582a2). As the script is not release on 
the html page I hope you are still working on it, but in the case you miss the 
point here is an output (errors are several line output instead of one, and 
some @_ loosing for the sub msg()):

 ./check_postgres.pl --dbuser cedric --action connection
Use of uninitialized value within @_ in substitution iterator at 
./check_postgres.pl line 721.
POSTGRES_CONNECTION OK: DB "postgres" version  | time=0.12


./check_postgres.pl --dbuser cedric --action backends
     1 | 100      | postgres
     1 | 100      | cedric

POSTGRES_BACKENDS OK:  2 of 100 connections (2%) | time=0.05  postgres=1 
cedric=1
