Unable run \copy command via PGconn.( exec || query )

Hi ,
I am facing problem while executing following code :

require ‘postgres’
obj = PGconn.new( ‘192.168.1.156’,5432 ,’’,’’,‘tikono’,‘tikono’,‘tikono’
)
a = “\COPY
ivr_interface.call_flow(ref_id,loaded_time,menuid,expected_dtmf,expected_dtmf_status,processing_input,confirmation,external_staus,external_value)
from ./backupFiles/ivr_interface.call_flow.new WITH DELIMITER ‘$’ NULL
‘nil’”
p a
obj.exec( a )
p obj.methods

Error :
query.rb:5:in `exec’: ERROR: syntax error at or near “” at character 1
(PGError)
from query.rb:5
X=============================X

If I use “\copy …” , Instead of “\copy” then I got
query.rb:3: Invalid escape character syntax
a = “\COPY
ivr_interface.call_flow(ref_id,loaded_time,menuid,expected_dtmf,expected_dtmf_status,processing_input,confirmation,external_staus,external_value)
from ./backupFiles/ivr_interface.call_flow.new WITH DELIMITER ‘$’ NULL
‘nil’”

Note : Not PGERROR

If I use ,
‘\COPY
ivr_interface.call_flow(ref_id,loaded_time,menuid,expected_dtmf,expected_dtmf_status,processing_input,confirmation,external_staus,external_value)
from ./backupFiles/ivr_interface.call_flow.new WITH DELIMITER ‘$’
NULL ‘nil’’

I got the Error as ,
query.rb:5:in `exec’: ERROR: syntax error at or near “” at character 1
(PGError)
from query.rb:5

Can anyone tell me How to escape this \copy in PGconn.( query|| exec )
method ?

cheers,

all of the *** commands are implemented by the psql command line
program, not the database, so none of them will ever work with a raw
connection. fyi.

Thanks for your response . But I found the solution using psql command .
That is ,
psql -A -c “\COPY
ivr_interface.call_reports(pbxid,channeltype,callerid,calledid,landedtime,endedtime,endstatus,endreason,progresslangauge,defaultlanguage,internalerror)
from ./backupFiles/ivr_interface.call_reports.new WITH DELIMITER ‘$’
NULL ‘nil’” -q -t -h 192.168.1.156 -U tikono tikono"
