The select as sentence is used for generated
"temporary" or cached tables.
Some tables are very big and generate great quantity
of data, for that reason the wal for this tables
grows.
This information is useless for backup
and is useless to keep it.
I explore memcached option or pgmemcache proyect.

any sugestion are welcomed.
best regads,
