command not executing when called from a case statement in bash

Question

I'm stuck and trying to troubleshoot why the command within the case statement will not execute within this bash script.

If I copy and paste the command into the command line and hardcode the value it will work. Example: psql -h mycluster-1.us-east-1.redshift.amazonaws.com -U masteruser -d dev -p 5439 -v v1="foo_bar" -f getTableDetails.sql

In the script, I encased the command within parentheses for possible whitespace issues:

    #!/usr/local/bin/bash

    set -e
    set -x


    cluster_to_endpoint() {
      case "$1" in
        c01)
          RUNCMD=$(psql -h mycluster-1.us-east-1.redshift.amazonaws.com -U masteruser -d dev -p 5439 -v v1="$NAME" -f getTableDetails.sql)
          ;;
        c02)
          RUNCMD=$(psql -h mycluster-2.us-east-1.redshift.amazonaws.com -U masteruser -d dev -p 5439 -v v1="$NAME" -f getTableDetails.sql)
          ;;
      esac
    }


    while getopts ":c:n:" opt; do
      case $opt in
        c) cluster="$OPTARG";;
        n) name="$OPTARG";;
        *) usage
           exit 1
           ;;
      esac
    done

I am executing the script like so: ./myscript.sh -c c01 -n foo_bar

I've also tried just removing the () as well:

c01) 
   psql -h mycluster-2.us-east-1.redshift.amazonaws.com -U masteruser -d dev -p 5439 -v v1="$NAME" -f getTableDetails.sql;;

It looks like the variables are set.

$ ./myscript.sh -c c01 -n foo_bar
+ getopts :c:n: opt
+ case $opt in
+ cluster=c01
+ getopts :c:n: opt
+ case $opt in
+ name=foo_bar
+ getopts :c:n: opt

So why isn't the command executing? Thanks.

未执行的命令位于函数cluster_to_endpoint ，该函数从未调用过。
