Thread: undefined reference to `pg_snprintf when we upgraded libpq version from 10.3 to 12.3

Hi,

Did you also upgrade the libpq devel package?

To start, what distribution are you using, and how did you upgrade?
Are you using RHEL or Debian based packages? Did you upgrade libpq
using packages (yum/dnf update libpq or apt upgrade libpq)?

In any case, this seems like a problem with development package from a
different version then the library installed.

Kind regards, Martín
