Hi all,

I installed the module (I'm at CentOS 6.6) by yum install luasql-postgres, ok. 
Then I used:

lua     myscript.lua
/usr/bin/lua    myscript.lua
/usr/local/bin/lua myscript.lua

I discovered that it is version dependent: lua (=/usr/local/bin/lua) does not 
operate, it is 5.3, whereas /usr/bin/lua works ok, it is 5.1.
At the command line, it is not a problem to choose another lua interpreter than 
the default one is.
But if I use the same lua script within the ConTeXt, I came across the same 
problem because the default version in ConTeXt is 5.2.

First, I thought about the way how to change version of lua inside the current 
version of ConTeXt  (is it possible?)
but the same behaviour appeared when I tryed older versions (TL 2010, 2011, 
2012) containing lua v5.1 by the default. 
It seems that file postgres.so which is the main important is not visible for 
ConTeXt.

Neither
         package.path = '/usr/lib/lua/5.1/luasql;', 
not copying the postgres.so to the current directory did not help. 

I have any clue how to fix it. Have you any ideas?

Thanks in advance,

Tomáš
