Are we deparsing the names of the SQL files to infer the set of version numbers we have to worry about? It seems to me that if there's a list of known version numbers somewhere, we can use dash as the separator without any special restricton. For example foo-bar-baz-bletch.sql is either an upgrade script from version bar-baz to version bletch, or else it's an upgrade script from bar to baz-bletch. But presumably no real-world cases will actually be ambiguous, assuming any sort of half-way sane version numbering scheme. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
