```SQL
SELECT textlike(command, citus.grep_remote_commands)
```
And, if returns true, the command is logged. Else, the log is ignored.
When citus.grep_remote_commands is empty string, all commands are
logged.
This UDF coordinates connectivity checks accross the whole cluster.
This UDF gets the list of active readable nodes in the cluster, and
coordinates all connectivity checks in sequential order.
The algorithm is:
for sourceNode in activeReadableWorkerList:
c = connectToNode(sourceNode)
for targetNode in activeReadableWorkerList:
result = c.execute(
"SELECT citus_check_connection_to_node(targetNode.name,
targetNode.port")
emit sourceNode.name,
sourceNode.port,
targetNode.name,
targetNode.port,
result
- result -> true -> connection attempt from source to target succeeded
- result -> false -> connection attempt from source to target failed
- result -> NULL -> connection attempt from the current node to source node failed
I suggest you use the following query to get an overview on the connectivity:
SELECT bool_and(COALESCE(result, false))
FROM citus_check_cluster_node_health();
Whenever this query returns false, there is a connectivity issue, check in detail.
PostgreSQL does not need calling this function since 7.4 release, and it
is a NOOP.

tuplestore_donestoring() isn't needed anymore, but provide a no-op
macro definition so as not to create compatibility problems.

We had 2 class definitions for CitusCacheManyConnectionsConfig, where
one of them was a copy of CitusSmallCopyBuffersConfig.
This commit leaves the intended class definition that configures caching
many connections, and removes the one that is a copy of another class
Since sequences are not marked as distributed while creating table if no
metadata worker node exists, we are marking all sequences distributed
while syncing metadata explicitly.
We've both allowed delegating functions and procedures from worker nodes
and also prevented delegation if a function/procedure has already been
propagated from another node.
Before that PR we were updating citus.pg_dist_object metadata, which keeps
the metadata related to objects on Citus, only on the coordinator node. In
order to allow using those object from worker nodes (or erroring out with
proper error message) we've started to propagate that metedata to worker
nodes as well.
