Why does Citus error with certain boolean constraints?

Question

If I run this query:

SELECT "t1"."id" FROM "session" AS t1 WHERE ("t1"."dirty" = TRUE) ORDER BY "t1"."id" LIMIT 1000;

I get the following error:

Error : ERROR:  unsupported clause type

This query works perfectly on a local table. Why is Citus raising an error when I use it on a distributed table?

Answer 1

instead of:

"t1"."dirty" = TRUE 

use:

"t1"."dirty" IS TRUE
