[GENERAL] Corrupted Dabatabase
Hello Everydody, My database is corrupted, each time i try to list all the tables in the database i have got the following message hla2db=> \d ERROR: could not open relation 1663/16385/1255: Read-only file system I read that my best option is to use my backup. Before using my backup i would like to remove all databases in postgresql and create everything again from scratch. Unfortunatlly i can't see the list of databases, althought i am able to create databse can you suggest what to do? is it a good idea to reinstall postgresql?

Re: [GENERAL] conditional insert
i don't see it clear, let me put an example
i got the following table
molec varchar(30)
seq varchar(100)
where I insert my values
lets image that i have a record introduced as ('ubq', 'aadgylpittrs')
how i can prevent to insert another record where molec='ubq' ?
