Thread: [HACKERS] Gettting warning message during PostgreSQL-9.5 installation on Windows

Hi,

I am getting this warning message when trying to install
PostgreSQL-v9.5 on Windows with Perl-5.22 and above,

Unescaped left brace in regex is deprecated, passed through in regex;
marked by <-- HERE in m/Project\("{ <-- HERE 8BC9CEB8-8B4A-11D0-8D11
00A0C91BC942}"\) = "([^"]+)"/ at Install.pm line 220. Installing
version 9.5 for debug in
C:\Users\ashu\git-clone-postgresql\postgresql\TMP\test

Attached is the patch that fixes this issue.

Please note that from perl-5.26 onwards, this is considered as a
syntax error instead of warning.

Also, I could see that, there is already a git commit in
PostgreSQL-9.6 branch that fixes this but was not back patch to 9.5
and may be below branches.

    Silence warning from modern perl about unescaped braces

Mmm, yeah, we'd better fix it then, because people will surely try
to use older branches with current Perl.  Pushed.
