带有postgres-xl的zombodb：“ zombodb.so：未定义的符号：session_auth_is_superuser”

Question

I have a database cluster based on Postgres-xl 10. I have to create a search index by ZomboDB extension. I copied all extension files into /usr/local/pgsql/lib other than standard path of postgresql /usr/lib/pgsql/lib . Because I checked that postgres-xl uses different $libdir from postgresql.

When CREATE EXTENSION zombodb; , it gives error:

ERROR: could not load library "/usr/local/pgsql/lib/zombodb.so": /usr/local/pgsql/lib/zombodb.so: undefined symbol: session_auth_is_superuser

SQL state: XX000

How can I overcome this problem?

Answer 1

You can't use plugins or extensions for standard Postgres index's on Postgres-XL.

Posgres-XL is a distributed database. ie It is meant to have the data broken up over different nodes which means it's index's work in a completely different mannor with different settings requirements, and have to work across the coordinator nodes and the global transaction managers.

Unless this vender provides specific libs for Postgres-XL it is not going to work. Even if you could find a way to trick it into working it would be a REALLY bad idea. It could fail at any time because that software has never been tested to work like that.
