This PR puts infrastructure in place to walk pg_depend to figure out which dependencies to create on the workers. Currently only schema's are supported as objects to create before creating a table. We also keep track of dependencies that have been created in the cluster. When we add a new node to the cluster we use this catalog to know which objects need to be created on the worker. Side effect of knowing which objects are already distributed is that we don't have debug messages anymore when creating schema's that are already created on the workers.	2019-09-04 14:10:20 +02:00

Onder Kalaci	9a89c0b425	Fix bug while traversing the distributed deadlock graph With this fix, we traverse the graph with DFS which was originally intended. Note that, before the fix, we traverse the graph with BFS which might lead to killing some unrelated backend that is not involved in the distributed deadlock.	2018-01-22 08:45:48 +02:00
