Re: [PATCH] Add pg_get_policy_ddl() function to reconstruct CREATE POLICY statement

Hi Hackers,

Added a new #define GET_DDL_PRETTY_FLAGS because the existing #define GET_PRETTY_FLAGS is not suitable for formatting reconstructed DDLs. The existing #define GET_PRETTY_FLAGS always indents the code, regardless of whether the flag is set to true or false, which is not the desired behavior for pg_get_<object>_ddl functions.

Updated the logic of the get_formatted_string function based on Tim Waizenegger’s suggestion.

I am attaching the new v6 patch, which is ready for review.

I’ve incorporated your changes and prepared a combined v5 patch. The v5 patch is attached for further review.

Kinda sorta similar thought, I've noticed some existing functions like
pg_get_constraintdef make the "pretty" flag optional, so I'm wondering
if that scheme is also preferred here.

I've attached a small diff to the original
0001-Add-pg_get_policy_ddl-function-to-reconstruct-CREATE.patch to
illustrate the additional work to follow suit, if so desired.

Regards,
Mark
