Hi, @prateek_gupta . Do you mean the target is JSON? The JSON target would not be compatible with transforms or analyze - since that is a file-based target which does not support SQL. (Our docs should probably be more clear about this.)
In regards to the conflict between PGadmin and Meltano UI, I'm not sure I fully understand the issue but it sounds like the two may be trying to use the same local port. If so, the link to Meltano UI might direct you to PGAdmin web portal, or vice versa.
