Description:
I'm inquiring because I have some problem getting parallel processing to run
effectively in PostgreSQL.
This is not the right place to seek support. We have a -general mailing list for that.
How can I increase the Workers Launched value to match the Workers Planned
value, or at least raise it to 4?
That level of control is not provided.
I want to use parallel to speed up for index creation and data insertion
This page clearly states that data writing is not parallelized.
