Transaction ID's and Vacuum

[Samuel Stearns <SStearns@xxxxxxxxxxxxxxxx>]

Howdy,

 

I’ve got an old 7.4.5 instance of Postgres running on Linux.  My transaction ID’s are just over the 1 billion mark.  I ran an instance wide vacuum analyse but this had now effect on the transaction ID count.  Do I need to run a vacuum full?

 

Thanks,

 

Sam
