I use vim's :! external command function all the time, usually providing % as an argument to the shell command. For example :
:!psql -f %
I also have a lot of bash shell functions in my .bashrc that I use. For example:
psql-h1 ()
{
/usr/bin/psql -hh1 -d mydb "$@"
}
These bash functions aren't available from :! inside of vim. Is there a way to make them available?

Finally you just have to add the source ~/bin/functions.sh line to your . bashrc file. This way you will be able to call them from the command line, your . bashrc will stay clean, and you will have a specific place for your personal functions.
To invoke a bash function, simply use the function name. Commands between the curly braces are executed whenever the function is called in the shell script. The function definition must be placed before any calls to the function.
Creating a Function in Bash The code between the curly braces {} is the function body and scope. When calling a function, we just use the function name from anywhere in the bash script. The function must be defined before it can be used.
Export your functions. That is:
psql-h1() { /usr/bin/psql -hh1 -d mydb "$@"; }
export -f psql-h1 ### <-- THIS RIGHT HERE
This will make them available to any copy of bash run as a child process, even if it's a noninteractive shell and so doesn't read .bashrc.

An alternative to exporting your functions (which may no reach Vim is there's a non-Bash shell in between; see here for such a case), you can instruct Vim to start an interactive shell, so that your .bashrc is read. Just pass the -i flag to Bash, via Vim's :help 'shellcmdflag'.
