Seems entirely reasonable to me, provided that we only update the
extensible-options syntax:
VACUUM [ ( option [, ...] ) ] [ table_and_columns [, ...] ]
I don't want to add any more options to the older syntax:
VACUUM [ FULL ] [ FREEZE ] [ VERBOSE ] [ ANALYZE ] [ table_and_columns [, ...] ]
I am slightly confused as to how we got on to this topic since the
subject is "Vacuum crashes", but perhaps Lyes was simply speaking
imprecisely.
