Compilation of port php82-pgsql ends in error for undeclared identifiers

Context: FreeBSD 13.2-RELEASE-p8 GENERIC amd64

I'm trying to install from the port phppgadmin that I know requires a 
php8x-pgsql dependency.

Unfortunately

/usr/ports/databases/php82-pgsql % sudo make install

Where am I wrong? And what should I do to solve this compilation error?

Thank you
