I ran posgress 8.3. I have a database about 90Mb. 23066 sequences and 2083 table When I back up the data it says this error. out of shared memory
help me
230000 sequences is... A lot :)
That said, the error message gives you a hint of what to try. Did you try to increase max_locks_per_transaction as it says?
And as has been already said, your 8.3 version is extremely out of date. It went out of support in 2013, coming up on 8 years ago. You need to upgrade that right away -- but of course, you need to dump your data in order to do that....
