Comment(by strk):

 Now you are a sed hacker you could try with that. Who needs perl anymore !
 :)

 How does "ALTER EXTENSION UPDATE" know if it's possible to update w/out
 dump-reload ?

 In other words.. how do we do when we _need_ to change something in CREATE
 TABLE / CREATE TYPE. For example you just droped an ALTER TABLE ADD COLUMN
 of mine (for topology.topology) which was there for the specific purpose
 of keeping the .sql file usable for upgrading since the stone-age of
 topology. That one was an update adding
 a field to topology.topology. How is that done with ALTER EXTENSION ?
