Re: Passwordcheck Extension Not Installing

Hi Tom,

Thank you for your response. My *postgresql-contrib* package and PostgreSQL
versions appear to be compatible, as shown below. Additionally, other
extensions are installed in the *"/usr/share/postgresql/17/extension/"*
directory.

I have also observed that the *passwordcheck.so* file exists in the
*"/usr/lib/postgresql/17/lib/"* directory. It seems that, for some reason,
when the PostgreSQL service starts, it is unable to read the
*passwordcheck.so* file and create the *passwordcheck.control* file in the
*"/usr/share/postgresql/17/extension/"* directory. I don't think this issue
is due to a missing package; it appears to be a general problem.
