Also, but that's a nitpick perhaps not relevant to your use case:

This

        $> psql -d gnumed_v22 -U <redacted>
        psql (11.5 (Debian 11.5-1+deb10u1))

        gnumed_v22=> select 'infinity'::timestamptz;
        -[ RECORD 1 ]---------
        timestamptz | infinity

        gnumed_v22=>

is the highest timestamp.

(You *can* count the horses in *your* corral but there's
 always more of them elsewhere ;-)

Just so you are aware.

Best,
Karsten
