Logged by: Paul Deschamps
Email address: pdescha...@gmail.com
PostgreSQL version: 8.4.6
Operating system: Ubuntu 10.4
Description: Running postgress in a shell script fails
Details:
When running postgres in a shell using the -c option it looks as though it
parses the contents of the --command as command line arguments.
---BEGIN SCRIPT---
#!/bin/bash
psql --version
PCOMMAND='psql postgres -c"SELECT tablename FROM PG_TABLES limit 1;"'
echo "PGSQL - Execution from a shell script test"

echo "TEST 1 "
OUTPUT1=$(${PCOMMAND})
echo $OUTPUT1

echo "TEST 2"
OUTPUT2=`$PCOMMAND`
echo $OUTPUT2
echo
echo "TEST 3"
OUTPUT3=`exec $PCOMMAND`
echo $OUTPUT3
echo
echo "TEST 4"
$PCOMMAND
echo "TEST 5"
psql postgres -c"SELECT tablename FROM PG_TABLES limit 1;"
