Re: Inline non-SQL SRFs using SupportRequestSimplify - Mailing list pgsql-hackers

I share this opinion. In fact, in the existing tests, if test_inline_in_from_support_func is triggered, 
the input parameters are necessarily of type TEXT—so there’s no need for an additional type check.

How about changing it to the following?
```
