Hi
(sorry forget to cc the hacklist)
> Improve psql \df to choose functions by their arguments
I think this is useful.
I found some comments in the patch.
1.
> * Abbreviations of common types is permitted (because who really likes
> to type out "character varying"?), so the above could also be written as:
some Abbreviations of common types are not added to the type_abbreviations[] Such as:
Int8 => bigint
Int2 => smallint
Int4 ,int => integer
Float4 => real
Float8,float,double => double precision
(as same as array type)
Single array seems difficult to handle it, may be we can use double array or use a struct.
2.
And I think It's better to update '/?' info about '\df[+]' in function slashUsage(unsigned short int pager).
Best regards,
houzj
