I'm a bit confused about blob and large datatypes references that i
found in postgres documentation. I've looked at the documentation but
there are no data type blob. As i read on, someone was mentioning about
blob and bytea. Are they the same? is there any other large
datatypes? The reason is because i wanted to know what datatypes will
not be processed by pg_dump by default unless i set the -b option.
Since the docs mentions blob or large datatypes, i was wondering which
one is it rather than just using -b for the sake of safety but not
knowing if it is useful or not?
