Hello David and Fabrízio,
The names of the tables and indexes differ from the original script. Only the names.
This is the query plan for only 19684 rows.
I have another query running for around 30000 rows, but it takes an eternity to finish.
If it finishes in acceptable time I'll make it available to you.
As in previous times when trying to optimize, I submitted this execution plan to https://explain.depesz.com but now, as it happened then, I am not able to extract information to decide me on what to do or to decide on a path leading to optimization.
The environment conditions are exactly the same as described in my previous message.
Thank you in advance for your attention and help.
They will be greatly appreciated.
Dias Costa

The names of the tables and indexes differ from the original script. Only the names.
This is the query plan for only 19684 rows.
I have another query running for around 30000 rows, but it takes an eternity to finish.
If it finishes in acceptable time I'll make it available to you.
As in previous times when trying to optimize, I submitted this execution plan to https://explain.depesz.com but now, as it happened then, I am not able to extract information to decide me on what to do or to decide on a path leading to optimization.
The environment conditions are exactly the same as described in my previous message.
Thank you in advance for your attention and help.
They will be greatly appreciated.
