compatibility with recent versions of PostgresQL

[alegian]

I have successfully ran the project with an external Postgres database in tha past.
Unfortunately this time I am obligated to use Postgres version 15.
All things kept constant, just trying to connect gives the error

Unable to connect to PostgreSQL server: SCRAM authentication requires libpq version 10 or above.

I think this has to do with the old versions of libraries being used in the project.
Is there some way to update said libraries, or just allow this connection?
