[postgis-users] Is 2.1.8 stable?

My 2 cents.:

My recent [bad] experience with a Postgis bug, described in my email to
this list last week, was on 2.1.8 (but running on Windows 7, not Solaris).
Fortunately for me, I was just using it to do a little GIS hacking on my
desktop. But after my experiences of the last few weeks, it would take a
lot of convincing to get me to use Postgis 2.1.8 in a production
environment. (Although, supposedly, the bug I encountered was also present
in 2.1.2, so YMMV.)

> Hello,
> We recently upgraded from 32bit PostgreSQL 9.3.4 + PostGIS 2.1.2 to 64bit
> PostgreSQL 9.4.4 + PostGIS 2.1.8. All the required packages for PostGIS
> were upgraded to their latest versions. This is on Solaris 10 with the gcc
> that ships by sun (v3.x)
> All went well, except when we did regression testing we noticed  a complex
> spatial query that goes from geometry to geography and back (with SRID
> changes along the way) was crashing PostgreSQL. We broke down that code to
> simpler pieces and it worked, but later we found other code that worked
> before that would crash the database backend process too.
> Unfortunately our application is complex to the point that we haven't been
> able to distill the query down to something simple that I can open a ticket

> give some clues (if things go back to being stable.)
> Any experiences with 2.1.8 with regards to stability that you can share?
> We haven't tested 2.1.5, I'll update on how that goes.
