Re: sequence last_value

thanx to all for the replies

fixed the problem by manually (postgres would not allow me to get a script
(PHP) to do it) repeating an insert sql command until the last_value field
on location_key_location_seq was above 47. (the last index) haven't had any
more problems.

still a little worried about how this happened and thank goodness the table
was small and not the cable information table.

was giving me the same error, found that if I added the index it worked,
provided that the index was not in use. but who wants to find the last index
every time you do an insert :{

for a long time and thanx to your mail he is gona do it.

you have to otherwise postgres will not allow you to recreate the table, it
looks as if postgres drop's the index (_pkey) table when the table is
dropped, is this correct? and when you say explicitly is this the same as
drop sequence?
