This is a good solution as long as none of the column data includes
comma characters.
Since commas are more likely to occur in CHAR/VARCHAR/TEXT/etc.
columns than tabs, I suggest using something like this instead
(assuming none of your columns contain tab {ASCII 9} characters):
database=> \pset fieldsep '\t'
Field separator is " ".
database=> \a
Output format is unaligned
database=> \o table.tab
database=> TABLE table;
database=> \o
