DuplicateColumnProjection in valid query

[egg-juxt]

DBeaver makes this request at init-time:

SELECT db.oid,db.* FROM pg_catalog.pg_database db WHERE 1 = 1 AND datallowconn AND NOT datistemplate OR db.datname =$1
ORDER BY db.datname

which causes the error

16:38:09.889 [pgwire-connection--pool-10-thread-1] ERROR xtdb.pgwire - #xt/illegal-arg [:xtdb/sql-error Errors planning SQL statement:
  - Duplicate column projection: oid {:errors [#xtdb.sql.plan.DuplicateColumnProjection{:col-sym oid}]}]
