Hi,
suppose I have a let's say heavy used table. There's a column containing
UNIQUE in4
values. The data type musn't exceed 32-Bit. Since however the table is heavy
used 2^32 will be reached soon and then? There are far less than 4G-records
saved thus these values may be reused. How can this be accomplished?
I already defined a sequence but then?
I appreciate your help.

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
