[check_postgres] nagios output for backends

[Cédric Villemain]

Hi,

here is a first patch for nagios output of backends check.

It try to follow the nagios guidelines but fail...
In fact, output should be 'label'=value[UOM][;warn][;crit][;min][;max]
But all MUST be of the same UOM (unity of measurement), and actually it is not 
possible to output % wihtout redisign the check_backend (and I don't want to 
rewrite it right now), and the warn,crit,min and max are global not for each 
DB.
So the output with this patch is : 
 'label'=value;warn;crit;0;max 
where warn,crit and max are for total connections, not by each database(side 
note : allow plugin to check warn;crit by DB ?). And percentage are converted 
to absolute value, also minus are reverted.
