I just pulled info from my old memory in my previous mail. Now the following links seem to be relevant. (They should be different from what I saw in the past.) https://ml.postgresql.jp/pipermail/pgsql-jp/2007-January/013103.html https://teratail.com/questions/295988 IIRC, the open source Postgres extension EUDC also uses CREATE CONVERSION.
