Hi,

Tab completion for ALTER FUNCTION/PROCEDURE/ROUTINE action was
missing, this patch adds the tab completion for the same.

Hi,
I applied your patch and did some tests.
Is it okay not to consider SET and RESET commands? (e.g ALTER FUNCTION)

Those also should be handled, attached v2 version includes the changes
for the same.

The basic options supported by PROCEDURE are a subset of ROUTINE with a
difference of COST, IMMUTABLE, [NOT] LEAKPROOF, ROWS, STABLE
and VOLATILE.

The basic options supported by ROUTINE are a subset of FUNCTION with a
difference of { CALLED | RETURNS NULL } ON NULL INPUT, STRICT and
SUPPORT. Is it worth refactoring a bit with common lists?

+       "RESET", "RETURNS NULL ON NULL INPUT ", "ROWS",
Extra space after INPUT here, that's easy to miss.

Good catch, the attached v3 patch has the changes for the same.

Hi Vignesh,

Looks like the patch needs a rebase.

Also one little suggestion:

+ if (ends_with(prev_wd, ')'))

+ COMPLETE_WITH(Alter_routine_options, "CALLED ON NULL INPUT",
+  "RETURNS NULL ON NULL INPUT", "STRICT", "SUPPORT");

What do you think about gathering FUNCTION options as you did with ROUTINE
options.
Something like the following would seem nicer, I think.

#define Alter_function_options \

Alter_routine_options, "CALLED ON NULL INPUT", \

"RETURNS NULL ON NULL INPUT", "STRICT", "SUPPORT"

Best,

I did not make it as a macro for alter function options as it is used
only in one place whereas the others were required in more than one
place.
The attached v4 patch is rebased on top of HEAD.

Okay, makes sense.

I tested the patch and it worked for me.

only in one place whereas the others were required in more than one
place.

My feeling is that having this macro somewhat improves readability and
consistency between the 3 cases, so I think it's worth it, even if
it's only used once.

I think it slightly improves readability to keep all the arguments to
Matches() on one line, and that seems to be the style elsewhere, even
if that makes the line longer than 80 characters.

Also in the interests of readability, I think it's slightly easier to
follow if the "ALTER PROCEDURE <name> (...)" and "ALTER ROUTINE <name>
(...)" cases are made to immediately follow the "ALTER FUNCTION <name>
(...)" case, with the longer/more complex cases following on from
that.

That leads to the attached, which barring objections, I'll push shortly.

While playing around with this, I noticed that the "... SET SCHEMA"
case offers "FROM CURRENT" and "TO" as completions, which is
incorrect. It should really offer to complete with a list of schemas.
However, since that's a pre-existing bug in a different region of the
code, I think it's best addressed in a separate patch, which probably
ought to be back-patched.

OK, I've pushed and back-patched a fix for that issue too.
