That seems like a legitimate concern.  We usually try not to make
keywords more reserved in PostgreSQL than they are in the SQL
standard, and REPEATABLE is apparently non-reserved there:


This also makes "method" an unreserved keyword, which I'm not wild
about either.  Adding new keyword doesn't cost *much*, but is this
SQL-mandated syntax or something we created?  If the latter, can we
find something to call it that doesn't require new keywords?
