Bug fix for 7.4?

From
Michael Meskes
Date:
I just fixed a bug in ecpglib that caused it to misbehave for all
internal array/vector types. They were treated like the external ones.
So ecpg expected them to be listed as '{...}' which surely failed. 

However, this bug fix involves more code changes than I like to just
commit into 7.4 at this point of the release. So the fixes are so far
just committed to HEAD. On the other hand I don't like to release 7.4
with this know bug. 

The only solution I see is someone else looking over the patch resp.
testing it. It worked well with my test suite, but then this may not
catch all side effects.

Yep.  Send patch to patches list and/or have someone who is using this
functionality test it.

I looked over it, and the only part that seems odd is that you seem to
have removed the type info caching behavior in execute.c.  Is that
intended?  It looks like ECPGis_type_an_array() will now issue a query
on every call for a non-built-in type, which seems rather a large loss.
Also, if cache_head ever becomes non-null then it stops trusting its
internal knowledge as well, which seems worse.

Well actually no. I removed it for testing reasons but didn't re-add.

I re-added it. 

Memo to /me: Just testing it is not enough. Better to look over the code
again after a night of sleep.

Thanks a lot.
