[Postgres-xc-general] Questions about Postgres-XC

[Alan B. <ala...@hd...>]

I have a few questions about Postgres-XC that I couldn't find answers to in the documentation or with google searches:

- How does postgres-xc work with extensions, specifically PGQ? Do they work? Where do they "run?" on the data nodes or on the Coordinator?

- Similarly, how/where do user-defined functions get installed/run?

- And can user-defined functions perform DML and DDL?

- Can we shard on schema? (i.e. put some schemas in one location and other schemas in different locations, sharded the same way rows are?) Or if not, can we shard one table, and have functions execute on the same node as some controlling row?

Thanks,
