Thanks for answering, but
I didn't ask for a PostgreSQL client. I asked for the c-language-lib
libpq. (which is maybe used by some clients).
I would use the latest libpq, but I cant, because our c++-project stucks
in 32bit architecture. The latest 32bit pqlib is that from v10.

Can I access a PostgreSQL v13 Database with this pqlib safely?
