Hi Alexey,
Quick comment on this patch: recently, we've decided that having patches
replace the whole base script for an extension is too much of a
maintenance problem, especially when there are several patches in the
pipeline for the same contrib module. The new style is to provide only
a version update script (which you'd have to write anyway), and then
rely on CREATE EXTENSION to apply the old base script plus the update(s).
You can see some examples in the patch I just posted at
https://www.postgresql.org/message-id/24721.1505229713@sss.pgh.pa.us
Also, since that patch is probably going to get committed pretty soon, you
could reformulate your patch as an add-on to its citext--1.4--1.5.sql
script. We don't really need to have a separate version of the extension
for states that are intermediate between two PG major releases. Only
if your patch doesn't get in by v11 freeze would you need to make it a
separate citext--1.5--1.6.sql script.
regards, tom lane
