Hi Laurenz
Many thanks for your reply.
Could you please bit more explain about the following sentence you wrote:
There are no performance problems except the ones that always come with an
index: INSERTs, UPDATEs and DELETEs will be slower and do more disk I/O and
locking.
Every index you add slows down modifications to the table a little bit,
because it has to be kept up to date. It also uses more disk space and
takes time for VACCUM.
