Excuse me for asking, but could you explain what is the purpose? Which is true, "upgrade to 9.1 from past versions" or "upgrade from 9.1 to future versions"? Also, how much advantage will we have compared with uninstall_MODULE.sql + CREATE EXTENSION? In my understanding, the patch does two things: 1. Add ALTER object SET EXTENSION 2. Add MODULE.upgrade.sql script for each contrib module #1 seems reasonable as a supplement for CREATE EXTENSION patch, but we might need not only "attach" but also "detach". I guess #2 is much more difficult than expected because we might upgrade databases from older versions. Will we need upgrade script for each supported versions? -- if so, it would be nightmare... -- Itagaki Takahiro -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
