The previous coding would result in deleting and not re-creating the extension membership pg_depend rows, since there was no CommandCounterIncrement that would allow recordDependencyOnCurrentExtension to see that the deletion had happened. Make it work like the shell type case, ie, keep the existing entries (and then throw an error if they're for the wrong extension). Per bug #6172 from Hitoshi Harada. Investigation and fix by Dimitri Fontaine.
