PHP not loading php_pgsql.dll on Windows

Question

PHP 5.2.8 is refusing to load php_pgsql.dll, with the following error:

Warning: PHP Startup: Unable to load dynamic library \'D:\\PHP\\ext\\

Answer 1

This happened to me also with PHP 5.4.1

Copying the offending DLL everywhere didn't work, and I don't have PostgreSQL installed in the server, but I also planned to use PHP against different Postgres versions, so the only solution I found that worked was to put in httpd.conf a line like this:

LoadFile "C:/Program Files/PostgreSQL/8.4/bin/libpq.dll"

And referring to the libpq.dll that comes bundled with PHP, like this:

LoadFile "C:/php/libpq.dll"

After that it worked fine to me.
