I use Intellij Idea Ultimate 2016.3 version. I try to connect to Postgres DB using the Intellij Idea's default "Database" plugin. However when i try to sync with the DB, I see this in the event log:
ERROR: column reference "oid" is ambiguous Position: 1205.
I tried checking the logs and this is what I found.
Caused by: org.jetbrains.dekaf.exceptions.StrippedSQLException: org.postgresql.util.PSQLException: ERROR: column reference "oid" is ambiguous Position: 1205

Then I see there is a query like below getting executed.
The SQL statement:
select max(last_tx) as state_number from (select max(xmin::varchar::bigint) as last_tx
from pg_catalog.pg_type
where typnamespace = oid(?)
union all
select max(xmin::varchar::bigint) as last_tx
from pg_catalog.pg_class where relnamespace = oid(?)
union all
select max(xmin::varchar::bigint) as last_tx
from pg_catalog.pg_proc where pronamespace = oid(?)
union all
select max(xmin::varchar::bigint) as last_tx
from pg_catalog.pg_operator where oprnamespace = oid(?)

select max(A.xmin::varchar::bigint) as last_tx
