I have an Access database that I have exported to PostgreSQL via ODBC, which has worked ok & the data is in PostgreSQL but some of the column names were in mixed case e.g. AccountCode
When I look at the table definitions in pgadmin these are shown in quotes e.g."AccountCode" and any queries made that reference these columns require the quotes.
There are too many fields to issue alter table commands to rename in SQL so my question is , is it safe to use a query such as
select relfilenode from pg_class where relname='rates'
update pg_attribute set attname=lower(attname) where attnum >0 and attrelid=23424
