Hi John,

I can understand that we can't use \COPY command directly in a function. Could you please brief me your alternative
solutionwith a sample piece of code or any useful link? 

Thanks and Regards,
Siva.

\COPY is a psql metacommand, not a proper SQL command, its translated to
a SQL COPY command. you can't use \ commands in functions, so you'll
need to recode that as a COPY ... TO STDOUT ...; and recieve the stdout
stream and write it to your file (which is what the \COPY command is doing).
