pgsql: Fix memory leak when rejecting bogus DH parameters. - Mailing list pgsql-committers

Fix memory leak when rejecting bogus DH parameters.

While back-patching e0e569e1d, I noted that there were some other
places where we ought to be applying DH_free(); namely, where we
load some DH parameters from a file and then reject them as not
being sufficiently secure.  While it seems really unlikely that
anybody would hit these code paths in production, let alone do
so repeatedly, let's fix it for consistency.

Back-patch to v10 where this code was introduced.
