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
