You can get the same result with a query like this: select max(id) from ( select report_id as id from report union select chart_id as id from report_chart union select datasource_id as id from report_datasource union select group_id as id from report_group union select parameter_id as id from report_parameter union select reportuser_id as id from report_user ) The use of a temporary table is not required. You can get the same result with a query like this:

select max(id) from (
select report_id as id from report
union select chart_id as id from report_chart
union select datasource_id as id from report_datasource
union select group_id as id from report_group
union select parameter_id as id from report_parameter
union select reportuser_id as id from report_user
)

This alone would make it worth switching from Oracle to PostgreSQL, where you say: SELECT setval('report_report_id_seq', coalesce((SELECT max(report_id) FROM report), 1)) Oh, the humanity! This alone would make it worth switching from Oracle to PostgreSQL, where you say:

SELECT setval(’report_report_id_seq’, coalesce((SELECT max(report_id) FROM report), 1))
