Hello PGlist,
We are interested in migrate some data with identity/sequential columns
from a non PG database into PG database , tables with identity columns.
First Q is : are system generated/identity columns values supported in
PG8.4 if yes,
I would like to know if there is a option to control this values: aka :
can we set the identity value "off" while we are inserting some already
generated values and next turn "on" the identity column option in PG ?
next Q : can we set the gap of the values, and can we set what the next
generated value /start value to our choice?
Thank you
Isabella
