Nay,we have currently nice multi-line CREATEs.

the following python script should to work

------------------------------------------------------
#!/usr/bin/env python
 
import sys
 
in_data = 0
 
while 1:
    line = sys.stdin.readline()
    if not line: break
    if line[:5] == 'COPY ':
        in_data = 1
    if not in_data: sys.stdout.write(line)
    if in_data and line[:2] == '\\.':
        in_data = 0
-----------------------------------------------------

as you can probably guess it is used as 

stripdata.py <withdata.sql >withoutdata.sql

-------------------------
