Hi,
For one of my personal projects I am interested in using the
PostgreSQL planner as a standalone library. However, I would like to
run this as an embedded library instead of actually creating anything
on disk.
I've realized that postgres has several pg_operator, pg_class etc.
tables which it uses for query planning purposes. Is there any
PostgreSQL component interface whose implementation could be
overridden to not actually try to read these tables from disk but
instead read it from a custom memory region that is managed by my code.
Thanks!
Maybe you'd like to consider gporca
https://github.com/greenplum-db/gporca as an alternative. You may also
want to look at Calcite https://calcite.apache.org/docs/ if you were
more into the Java world.
