Thread: naming convention/mixed case
Hi I'm working on a project (http://mandible.sourceforge.net/)that uses postgres for a membership directory. The database being used as a starting example is currently an Access database, and the first naming standard I'm using is the Leszynski/Reddick one at http://msdn.microsoft.com/library/backgrnd/html/msdn_20naming.htm - especially since these are the conventions that are currently used in the access database. The problem is that postgres's handling of mixed case table names etc makes things quite complicated, as they have to be enclosed in double quotes: this makes tab completion useless in psql, and possibly complicates functions/triggers/etc, as they will need mixtures of double and single quotes. For example, creating sequences called "seqMemberId" made them hard to modify with nextval and setval, as the function uses single quotes already. For me, it's fine to just live with this, as I've started using that convention, but just for future reference, is there a naming standard that is better indicated for postgresql(and other unix friendly databases perhaps?), or is there a plan to get postgres naming to support mixed case more?

Doing so would make us less compliant with the SQL standard, so no, there aren't any plans to change that. regards, tom lane

Thanks for the information. Is there a standards compliant naming convention I can use as an alternative in future?

You can use mixed case if you want --- you just have to be absolutely consistent about whether you double-quote the names or not. FooBar is the same as foobar FooBar is NOT the same as "FooBar" You can write 'em with quotes if you want, or without if you want, but you have to do it the same way all the time. regards, tom lane
