Refactor error messages to reduce duplication
I also took the liberty of changing errmsg("COPY DEFAULT only available using COPY FROM") to errmsg("COPY %s cannot be used with %s", "DEFAULT", "COPY TO") because the original wording is unlike all other messages that indicate option incompatibility. This message was added by commit 9f8377f (16-era), in whose development thread there was no discussion on this point. Backpatch to 17.
