Fix unchecked return value from strdup
The pg_dump compression was using strdup() instead of pg_strdup()and failed to check the returned pointer for out-of-memory beforedereferencing it. Fix by using pg_strdup() instead which probablywas the intention here in the original patch.Backpatch to v16 where pg_dump compression was introduced.Reviewed-by: Tristan Partin <tristan@neon.tech>Reviewed-by: Nathan Bossart <nathandbossart@gmail.com>Discussion:https://postgr.es/m/CC661D60-6F4C-474D-B9CF-E789ACA3CEFC@yesql.seBackpatch-through: 16
