I have an script with many "\copy" commands. For example:

\copy privilegios from '/work/eclipse-workspace/Canoan
Server/database/load/privilegios.dat'
\copy privilegios_de_usuarios from '/work/eclipse-workspace/Canoan
Server/database/load/privilegios_de_usuarios.dat'
\copy classificacoes from '/work/eclipse-workspace/Canoan
Server/database/load/classificacoes.dat'
\copy tipo_de_produto from '/work/eclipse-workspace/Canoan
Server/database/load/tipos.dat'

This lines are OK. But when I remove the preceding backslash from them I get
the error that you mentioned.
