logs related to PAX
 - Currently, if a field is too long, it will be stored in a TOAST file. This 
TOAST is different from PostgreSQL's TOAST tables, and they only share the same 
name.
 - Unlike traditional heap tables, PAX format does not support `TOAST` fields. 
Currently, all column data is stored in the same data file.
 - The PAX format does not support data backup and restore using `pg_dump` or 
`pg_restore`. PAX tables are ignored during these operations.
-- PAX format does not support Write-Ahead Logging (WAL), so there is no data 
backup between the primary and mirror servers.

Review Comment:
   1. PAX supports WAL - so can we add this to the feature list or somewhere 
for a note?

   After confirmation with the engineer, now PAX does not support data backup 
and restore using `pg_dump`, but can use `pg_basebackup` to back up and restore 
data. We can improve this line too.
