[check_postgres] Could not parse psql output! on windows

[Lord, David]

Hello,

I'm getting the following message when I run a connection test:

~~~~
$ perl ./WHHT/Postgres/check_postgres-2.22.0/check_postgres-2.22.0/check_postgres.pl -H localhost -p 5432 -db postgres -u postgres --action connection

I'm using Gow-0.8.0 and strawberry-perl-5.24.0.1-32bit. 

However, if I run the same on Cygwin using postgresql-client v. 9.6.1.1, it works:

~~~~
$ perl WHHT/Postgres/check_postgres-2.22.0/check_postgres-2.22.0/check_postgres.pl -H localhost -p 5432 -db postgres -u postgres --action connection
Password for user postgres:
POSTGRES_CONNECTION OK: DB "postgres" (host:localhost) version 9.6.1, | time=20.19s
~~~~

I have tried a few obvious things with no success:

- Setting the DOS codepage: C:\>cmd.exe /c chcp 1252
- Running perl with various options to set the input line separator: perl -0x0d0a or -0x0d or -0x0a

Unfortunately, I need to run it on windows as that is where the monitoring software lives, and the people that support it will not allow Cygwin (I think it chews the CPU).

Any advice gratefully received.

Regards
