Hi all,
I am investigating the benefits of different profile-guided optimizations (PGO) and link-time optimizations (LTO) versus binary optimizers (e.g. BOLT) for applications such as PostgreSQL.
I am facing issues when applying LTO to PostgreSQL as the produced binary seems broken (the server dies quickly after it has started). This is definitely a compiler bug, but I was wondering if anyone here have experimented with LTO for PostgreSQL.
Thanks,
