Bug installing luasql-postgresql on Windows?

[AlexBertrand]

Hi, I'm failing to install the postgreSQL rock. Here're my steps:

Using"VS2013 x64 Cross Tools Command Prompt3", and entering the luarocks install luasql-postgres PGSQL_DIR="C:\Program Files\PostgreSQL\9.3" I get the message below.

Initially, when entering simply luarocks install luasql-postgres, I had the following message: Error: Could not find expected file pg_config.h, or pg_config.h for PGSQL -- you may have to install PGSQL in your system and/or pass PGSQL_DIR or PGSQL_INCDIR to the luarocks command. Example: luarocks install luasql-postgres PGSQL_DIR=/us r/local

Following the reply from luarocks-developers, this might be a bug in luasql.postgres and I should do a bug report/provide a pull request: http://sourceforge.net/p/luarocks/mailman/message/32917969/

Thanks for the support! Cheers, Alex

This problem was corrected in version 2.3.1. Check #42.
