It needs to be removed fromt he path of the server process if you want to use PL/Perl, PL/Tcl or PL/Python. If not, you should be ok having it ni there, just not during the installation. It should have no effect in the clients environment.

I'm installing psql to my laptop where cygwin is installed.
I got the warning for removing the cygwin\bin from the path
and re-start the installer.
It's not hard to remove cygwin from the path. Does qsql
need to remove cygwin permanently?
Thanks
