Subject: pgsql: Restore the ability to use | and -> as prefix operators.
Date: Sat, 18 Jul 2026 16:57:49 +0000
Message-ID: <E1wl8MG-000nYg-25@gemulon.postgresql.org> (raw)
Restore the ability to use | and -> as prefix operators.
Commit 2f094e7ac changed the parser to treat these as built-in
operator names, where before they were just generic Op. While
it correctly gave them the same precedence as Op and added new
productions to allow them to still be used as infix operators,
it missed allowing them to still be used as prefix operators.
At least one extension expects to be able to do that, so add
the necessary productions.
