Some useful validation functions in
https://github.com/apache/incubator-madlib/blob/master/src/ports/postgres/modules/utilities/validate_args.py_in
(look at the comments in the code for those functions, use if it applies to
your scenario):
```
table_exists
get_cols_and_types
columns_exist_in_table
is_col_array
is_var_valid
input_tbl_valid
output_tbl_valid
cols_in_tbl_valid
```
https://github.com/apache/incubator-madlib/blob/master/src/ports/postgres/modules/utilities/utilities.py_in:
```
unique_string
```
You could probably have one function to validate input all args, include
your current validations checks as part of that python function.
