7.3.1 BREAKS COMPATIBILITY with the latest PHP4 (due to libpq.so.[23])

The latest PHP4 (php-4.3.0) WILL NOT work with 7.3.1, since it (PHP)
expects there to be libpq.so.2, whereas 7.3.1 only provides libpq.so.3
...

... I am really astonished that I could not find anyone else who had this
problem. Am I doing something horridly wrong?

What can I do? I try ./configure'ing PHP, but it tells me:
gcc -o conftest -g -O2  -I/usr/pkg/include  -L/usr/pkg/lib
-R/usr/local/pgsql//lib -L/usr/local/pgsql//lib conftest.c -lpq -lcrypt
-lm  -lcrypt 1>&5
Shared object "libpq.so.2" not found

Complete debug.log installed.

PLEASE help...
