   I can't test previous versions of PostgreSQL. But it is pretty safe to say 
that it applies to all versions.
   
   Postgresql support export to CVS since version 8.0 (year 2005, 
https://www.postgresql.org/docs/8.0/release-8-0.html)
   In the documentation of 8.1 
(https://www.postgresql.org/docs/8.1/sql-copy.html), it didn't state clearly 
but implied that the CSV export will not escape special characters.  The 
backslash escape is used for import data from text file (COPY FROM) only.
   
   For text format (tab delimited), there is no reason to quote the text.
