Description of problem:
libpq is a client library that has been detached from the postgresql server, so we can link the other software with a single library and not introduce need to build with all available postgresql versions.
libpq library has history of being backward compatible, so a version from v12 works fine with version v10.
To ensure that it is working fine with the newest server version, we should update the libpq library for the latest version when introducing a new stream (which is being done via BZ#1721822).
Thus, this is a request to rebase the libpq component to the version that comes from postgresql v12.
