Unrecognized Node Type Warning

2023-05-18 Thread Arora, Nick
We are using PostgreSQL 12.13. We are noticing that queries that attempt to 
retrieve an element of an array by specifying its position cause a warning to 
be emitted: "WARNING:  unrecognized node type: 110".

Would appreciate your help diagnosing the issue and identifying steps to 
resolve.

Queries that reproduce the issue:

SELECT ('{0}'::int2[])[0];
WARNING:  unrecognized node type: 110
int2
--

(1 row)


SELECT ('0'::int2vector)[0];
WARNING:  unrecognized node type: 110
int2vector

  0
(1 row)

SELECT (indkey::int2[])[0] FROM pg_index limit 1;
WARNING:  unrecognized node type: 110
indkey

  1
(1 row)

SELECT scores[1], scores[2], scores[3], scores[4] FROM 
(select('{10,12,14,16}'::int[]) AS scores) AS round;
WARNING:  unrecognized node type: 110
WARNING:  unrecognized node type: 110
WARNING:  unrecognized node type: 110
WARNING:  unrecognized node type: 110
scores | scores | scores | scores
+++
 10 | 12 | 14 | 16
(1 row)

Hello Tom,

Thanks for the information.  Here are the extensions we are using:

uuid-ossp
pgcrypto
citext
btree_gin

The warnings did start emitting shortly after the installation of btree_gin, so 
it seems somewhat suspect

I don't see that here, so I'm guessing it's coming from some extension.
What extensions do you have loaded?

Node type 110 would be T_SubscriptingRef in v12, which is a type name
that didn't exist in earlier versions (it used to be called ArrayRef),
so it's not very hard to believe that some extension missed out
support for that type.  But the only core-PG suspect is
pg_stat_statements, and I can see that it does know that node type.
