Ignore verification columns for read-only cache updatessmh-verification-trigger-only-generation
Read-only cache receives invalidations on record updates via triggers
in Postgres. Currently the notifications are sent for any modification
to the records. The verification related columns are not relevant to
the operation of the cache so this commit ignores the changes to the
columns in the triggers.
