Comment(by strk):

 Overnight I've been thinking that the "source" version passed to
 postgis_proc_upgrade.pl to generate the *upgrade_<current>_minor.sql
 script is confusing, because a "minor" upgrade should be for upgrading
 from any 2.0.0 to any 2.x.x, while 2.1.0 to 2.1.x would be a "micro"
 upgrade.

 The way I encoded it, instead, was to assume "source" was == "target" for
 a "minor" upgrade, meaning that aggregates added in a minor release (for
 example) would never be added by the upgrade script.

 That said, I start wondering if we should do the version check at runtime,
 using DO constructs.
 Doing it at runtime would avoid proliferation of a lot of different X_to_Y
 combination scripts
