Subject: pgsql: Allow casting between bytea and integer types.
Date: Fri, 07 Mar 2025 09:35:16 +0000
Message-ID: <[email protected]> (raw)
Allow casting between bytea and integer types.
This allows smallint, integer, and bigint values to be cast to and
from bytea. The bytea value is the two's complement representation of
the integer, with the most significant byte first. For example:
1234::bytea -> \x000004d2
(-1234)::bytea -> \xfffffb2e
