Metric table_bloat_approx_summary_sql fails with Divide by Zero

[dtmdl]

Similar to #464 (get_table_bloat_approx_sql), the table_bloat_approx_summary_sql fails with a divide by zero error in some circumstances. I applied the same fix to the postgres 12 metric_su.sql, and it appears to work correctly.

What version is affected?

Thanks in advance

I encountered the problem using:

pgwatch2 1.9.0
postgresql 14.4

Not sure if it's limited to those versions, or just a problem with newly-created (empty) databases.
