[HACKERS] UNIQUE not unique with inheritance (workaround?)
Is there any workaround for this problem? I'm getting involved in a project where inheritance is an incredibly useful feature, but the non-unique issue could be a serious stumbling block. Is there any way to work around it with a trigger or something? ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])

Some drawbacks are that you can't automatically start/restart it from the postmaster and it will put a little more load on the network, but it seems to mostly solve the issues of blocked pipes and using too much cpu time on the database server. ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html

The header files in /usr/include now give an error if you try to build a kernel module that gets header files from there. So whether they were wrong in the past or not, they are now doing things the way you say is proper. ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html

But, it was very handy. (Once I finally figured out the format through trial and error, ouch!) It is very nice to be able to just dump tuples in, instead of having to format them to text, then the database has to put them back to binary again. So, an alternative with a clean interface would be very much appreciated.
