Thank you very much Holger for answering, I'll tell you... regarding your question about whether it has enough provisioned space to be able to do the vacuum, yes... yes it does.
Regarding your indication of the version we are working on, I know that 9.2 is out of all support and that its update is imminent... But that's how it is right now and I have to deal with it...
For this reason, I appreciate that you can even guide me to see what is happening or could have happened regarding the end of the process without the expected result, which is cleaning the table.
Thank you in advance for your help

Dear All,
Along with saying hello, I would like to consult about a failure that is happening to me with a PG 9.2 base and with a table that weighs 116GB and its index 13Gb, mounted on a Linux Centos 7.2 with 4Core and 32Ram.
The failure occurs mainly in that I execute a Vacuum Full on the table and it ends after 6 hours, but it does not clean anything. When checking the dead tuples I realize that they follow the same dirty records in the table. REF: (table of 420MM records with 20MM dead tuples)
I hope you can guide me in finding a solution to clean that table.
Greetings and many thanks to the Postgresql.org community

Hi Erik,
Does it end cleanly or with an error after 6 hours?
Do you have enough disk space for the vacuum full? The old and the newly written data have to exist at the same time. Only after a successful vacuuming the old data get deleted.
BTW, PG 9.2 has been out of service for quite some time. Only versions 11 to 15 are supported, with the support for version 11 lasting less than a year.
Kind Regards,
Holger

Scott Ribe is right, the percentage of dead tuples is not high. So there no real reason to change anything.
