The code that you posted doesn't provide enough details about the problem.
Your sample code starts with use strict, but you don't show how any of the
variables are declared.
If $cust_data is actually declared with my() outside the while loop, then
everything should work fine. Perhaps there is an error in your code?

the gist of your question appears to be unrelated to PgSQL.
