php-src/ext/dbx/dbx_pgsql.c
Marc Boeren 1a842c4ae6 Fixed compile errors for PostgreSQL support (Mc) 
Removed globals that Rui put in, and changed the dbx_get_row
to include a row_number (which PostgreSQL expects) (Mc)
Added source files to Makefile.in and dbx.dsp (Mc)
#Could someone please check if the PostgreSQL support works?
#And please, check your work _before_ you commit anything!
