Thread: pgsql: Allow MSVC .bat wrappers to be called from anywhere

Allow MSVC .bat wrappers to be called from anywhere

Instead of using a hardcoded or default path to the perl file the .bat
file is a wrapper for, we use a path that means the file is found in
the same directory as the .bat file.

Patch by Anton Voloshin, slightly tweaked by me.
