Thread: Unrecognized Node Type Warning

Unrecognized Node Type Warning

From
"Arora, Nick"
Date:

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)

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.

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'm quite certain that none of the last five are causing this,
so you need to take it up with whoever provides "azure".
