Duh! I just realized that what I proposed with system() is a command
line approach.
As David Johnston mentionned, you can use the SQL COPY command.
One thing to remember with the Perl DBI is that you can use a string
variable in the $dbh->do() command.
Perl uses 2 different string variable delimiters:
1) ‘ ‘ , which is exactly what you enter $s= ‘\copy * from foo as
json’; will send that to the database without the need for escaping
anything (unless you need to enter an actual ‘ in the command, in which
case method two is better)
The issue is \copy is not a SQl statement, it is a psql(Postgres command
line client) meta-command. This means it can only be used in psql.
