Bash script for fetching row from Postgresql - linux

Question

I have a Postgresql function which returns table of JSON strings.
I want to fetch those rows under the Linux platform and run CURL program for each string like this:
curl http://XXX.XX.XX.XX:XXXX/update/json -H 'Content-type:application/json' -d ['||solr_interface.dict_cursor_okpd_json()||']'
Do you have any example how to do this using say bash script?
Thanks in advise.

I've found solution. Maybe it will useful for somebody
#!/bin/bash
if [ $# != 2 ]; then
echo "Please select postgres procedure for data retrieving as first parameter"
echo "and Solr index name (dictionary or company) as second parameter"
exit 1;
fi
PSQL=/usr/bin/psql
DB_USER="xxxxxxxx"
DB_PASSWORD="xxxxxxxx"
DB_HOST="xxx.xxx.xxx.xxx"
DB_PORT="xxxx"
DB_NAME="portal_sources"
export PGPASSWORD=$DB_PASSWORD
$PSQL \
-X \
-h $DB_HOST \
-p $DB_PORT $DB_NAME \
-c "select 'curl http://xxx.xxx.xxx.xxx:xxxx/solr/$2/update/json -H ''Content-type:application/json'' -d ''['||$1||']'''" \
--single-transaction \
--set AUTOCOMMIT=off \
