dev-db/postgresql: Multiple Fixes/Improvements

Bump to EAPI 7. Use ver-cut instead of versionator.

Preserve libpg{port,common}.a as they're needed by some PGXS builds.

Add Python 3.7 support. Thanks to Jeff Kowalczyk for verifying.

Allow ICU collations via icu USE flag.

Add debug use flag to allow debugging of extensions.
