True, but Counties has about 8 or 9 rules, view, or pk constraints attached to it. I don't want to break all these unless I knew of a way to save off the SQL for them beforehand so I can easily rebuild them...

Subject: [SQL] Replacing a table with constraints


I have a table called Counties which partially contains a lot bad data. By" bad data", I mean some records are missing; some exist and shouldn't; and some records have fields with erroneous information. However, the majority of the data in the table is accurate. I have built/loaded a new table called newCounties with the same structure as Counties, but contains no bad data. My was to completely replace the contents of Counties with the contents of newCounties. The problem is: several other tables have Foreign Key constraints placed on Counties. Therefore, Pg will not let me 'DELETE FROM Counties;", nor will it let me "DROP TABLE Counties;"

I'm perplexed. Can someone suggest how I can best get data from Counties to look just like newCounties?
