Bash function from psql (v14)

Hi,

I am trying to code bash function and call it from psql. But it is failing. How can I get this to work. Creating a separate script instead of a function works, but I do not want to do that. I have too many variables to be passed back and forth. Any ideas?

#!/bin/bash

psql -d postgres  -p 5433 <<-PSQLBLOCK

\! run-bash-function                                        -- This doesn’t work

PSQLBLOCK

# Run the function outside PSQLBLOCK. This works!

run-bash-function

exit $?

# Create bash function

run-bash-function ()

{

  echo "in bash function"

}

# end of bash script

Run the above script:

./test-bash-function.sh

sh: line 1: run-bash-function: command not found

in bash function
