I found it weird there's no simple way to check if a given string can be a PostgreSQL column name.

Although, to my understanding, you can escape with quotation marks some names that are otherwise invalid,

I don't think escaping such a thing is a good idea.

This validation is required if your column name can be dynamically generated.

# How to use

```python

>>> from is_valid_postgres_column_name import is_valid_postgres_column_name

>>> is_valid_postgres_column_name("column_A")

True

>>> is_valid_postgres_column_name("1column_A")

False

```

All PostgreSQL versions are supported. The only difference between versions, to my knowledge, are reserved keywords.

```python

>>> is_valid_postgres_column_name("window", version=13)

False

>>> is_valid_postgres_column_name("window", version=7.1)

True

```

# Installation

```shell

$ pip install -U is_valid_postgres_column_name

```

# Requirements

Python 3.0+

# Dependencies

None.

If you don't want to download additional library for such a simple thing, have a look at `sqlparse` [`keywords.py`](https://github.com/andialbrecht/sqlparse/blob/23d29933ddc4272b495d36e0e32d3eaf0c3ef76d/sqlparse/keywords.py) file.
