Subject: pgsql: Support multi-line headers in COPY FROM command.
Date: Thu, 03 Jul 2025 06:30:01 +0000
Message-ID: <E1uXDSK-004TEp-3A@gemulon.postgresql.org> (raw)

Support multi-line headers in COPY FROM command.

The COPY FROM command now accepts a non-negative integer for the HEADER option,
allowing multiple header lines to be skipped. This is useful when the input
contains multi-line headers that should be ignored during data import.
