RE: backend error after upgrading to 3.6.0

We don’t distribute postgis binaries for Debian/ubuntu systems.  That is done by apt.postgresql.org.  So they would need to make the change if any change needs made.

 

I think PostGIS works fine with any LLVM but it sounds like maybe PostGIS was compiled with  LLVM 14 and you have 15 installed.

That should be brought up on https://www.postgresql.org/list/pgsql-pkg-debian/ mailing list or it could just be a conflict with some other stuff you have installed that could be remedied switching apt priority settings.

Subject: backend error after upgrading to 3.6.0

 

I guess I found the issue. Seems like every time I send queries using PostGIS functions I get the following error:

 

error: Not an int attribute (Producer: 'LLVM15.0.7' Reader: 'LLVM 14.0.0')

 

The very first time it appeared is after upgrading PostGIS to 3.6.0. LLVM on my PostgreSQL instance is 'LLVM_CONFIG=/usr/bin/llvm-config-15'. 

 

Is it possible to make PostGIS 3.6.0 use LLVM 15?

 

 

P.S. Sorry for previously sending letters privately. It was by mistake.
