Re: Unable to create postgis 2.1.5 extension in PG9.2.8/rhel6

Hi David,

Thanks for the report, and analysis. I will update the PostGIS packages
to reflect that. It is bad that I did not catch this before.

I want to note that we always *assume* that people are using the latest
version of everything on their machines -- like we don't support RHEL
6.4 anymore :-)

(When I started building the RPMs around 10 years before, I used to
rebuild each RPM on every PostgreSQL update, since I used to maintain
only a few packages. Now, building each package would take significant
amount of time :-( )

Regards, Devrim

suggeststhat the postgis2_92-2.1.5 packages (and later) should have an RPM dependency of postgresql92 >= 9.2.9 to avoid
thiserror. There may be similar dependencies in other PG release streams, as it looks like that symbol also appeared
somewherebetween 9.3.0 and 9.3.5 as well.
