 	Adjusted to what value?

 	The call `require"luasql.postgres"' (note, without the 'l' at the
end) will search for the file luasql/postgres.so in your cpath and then
call the function luaopen_luasqlpostgres.  If you change the name of the
file, you'll have to change also the name of the function and recompile it.
If you've just mistyped the name (or can rename it back), the file should
be installed inside the luasql directory.  In your case, I think you'll
have to define package.cpath (LUA_CPATH environment variable) to:

LUA_CPATH=/home/mfritsche/lib/?.so

 	And then copy the binary library to:

/home/mfritsche/lib/luasql/postgres.so

 	Note that it does not have the 'lib' prefix.

 	Regards,
