Subject: pgsql: Make jsonb casts to scalar types translate JSON null to SQL NULL
Date: Fri, 24 Jan 2025 18:20:51 +0000
Message-ID: <E1tbOIV-003JUs-MO@gemulon.postgresql.org> (raw)
Make jsonb casts to scalar types translate JSON null to SQL NULL.
Formerly, these cases threw an error "cannot cast jsonb null to type
<whatever>". That seems less than helpful though. It's also
inconsistent with the behavior of the ->> operator, which translates
JSON null to SQL NULL, as do some other jsonb functions.
