Hi all,
I would like to create a library with UDFs written in C that implements
different Query Planner tasks (e.g. scan, hash, join, etc...). I am looking
for a document that provides an overview of execution flow within postgres
and the query planner. I am also looking for a description of the software
data structures and interfaces used.
Any references, suggestions or guidance would be appreciated.
Thank you in advance,
