Bug Description

postgresql-15 FTBFS with llvm-16.

The dh_auto_test run fails with erros such as:

client backend[34430] pg_regress/test_setup ERROR: could not load library "/<<PKGBUILDDIR>>/build/tmp_install/usr/lib/postgresql/15/lib/llvmjit.so": /<<PKGBUILDDIR>>/build/tmp_install/usr/lib/postgresql/15/lib/llvmjit.so: undefined symbol: LLVMBuildGEP

In LLVM changelog, at https://releases.llvm.org/16.0.0/docs/ReleaseNotes.html#changes-to-the-c-api, we can see that LLVMBuildGEP was removed in favor of LLVMBuildGEP2.

As reported upstream, at https://www.postgresql.org/message-id/flat/17927-2d7146227560bdf3%40postgresql.org, supporting LLVM 16 is not trivial and is being worked on for postgresql-16.

For now, we could just pin llvm 15 in mantic to avoid build failures.

The following upstream bug is also related: https://www.postgresql.org/message-id/flat/17929-71c7a59e1930980b%40postgresql.org

@Doko - subscribing you as FYI since you were so kind to let me know it is now the default.
Seems we need to pin llvm15 for Mantic - is that a problem for you?
