Обсуждение: extracting the sql for a function

Using postgres Version 9.5

I can extract the sql for a table using

pg_dump  -d database_name  -s  -t  table_name  -f  table_name.sql

Is there something equivalent for extracting the sql for a function from 
the database?

Using postgres Version 9.5

pg_dump  -d database_name  -s  -t  table_name  -f  table_name.sql

Is there something equivalent for extracting the sql for a function from the database?

select prosrc from pg_proc where proname = 'function_name';

You can pronamespace to WHERE clause to specify schema.

I don't know if there is but you can get the function definition:

SELECT * FROM pg_get_functiondef('functionname'::regproc);

or

SELECT * FROM pg_get_functiondef('functionname(list of parameters data types)'::regprocedure);

If you want to export you may use the -t and -o switches.
