Test the difference of performance between PostgreSQL varchar and uuid

[dadiorchen]

Now we are using varchar for trees.uuid, and use wallet.toekn.capture_id as a reference of trees.uuid, but it is in uuid type, so we need join data by: trees.uuid::text = token.capture_id::text to cast type and compare, we need find out the performance of this operation and potential optimization.

Please contact me for the db resources for testing
