This works:

Code:
#!/usr/bin/env bash

runMyProgram

if [ "$?" -ne 0 ]
then
    echo "bad"
else
    echo "good"
fi

Note: The $? variable is set to the exit status of the last command executed. So if you do anything after that and before the if, then you will skew the results.

PG_TRANSACTION_STATUS(3)												  PG_TRANSACTION_STATUS(3)

pg_transaction_status - Returns the current in-transaction status of the server.

SYNOPSIS
int pg_transaction_status (resource $connection) DESCRIPTION
Returns the current in-transaction status of the server. Caution pg_transaction_status(3) will give incorrect results when using a PostgreSQL 7.3 server that has the parameter autocommit set to off. The server-side autocommit feature has been deprecated and does not exist in later server versions. PARAMETERS
o $connection - PostgreSQL database connection resource. RETURN VALUES
The status can be PGSQL_TRANSACTION_IDLE (currently idle), PGSQL_TRANSACTION_ACTIVE (a command is in progress), PGSQL_TRANSACTION_INTRANS (idle, in a valid transaction block), or PGSQL_TRANSACTION_INERROR (idle, in a failed transaction block). PGSQL_TRANSACTION_UNKNOWN is reported if the connection is bad. PGSQL_TRANSACTION_ACTIVE is reported only when a query has been sent to the server and not yet com- pleted. EXAMPLES
Example #1 pg_transaction_status(3) example <?php $dbconn = pg_connect("dbname=publisher") or die("Could not connect"); $stat = pg_transaction_status($dbconn); if ($stat === PGSQL_TRANSACTION_UNKNOWN) { echo 'Connection is bad'; } else if ($stat === PGSQL_TRANSACTION_IDLE) { echo 'Connection is currently idle'; } else { echo 'Connection is in a transaction state'; } ?> PHP Documentation Group PG_TRANSACTION_STATUS(3)
