Hi,

we are upgrading postgresql from 9.2 to 12.2 and observed that
"regexp_split_to_table" functions is giving different output in 12.2 than
9.2.

This was intentional.  You will need to rewrite your query - probably by moving the call to regexp_split_to_table to the FROM clause and leveraging the LATERAL feature.
