I wonder if there's a difference in the implementation(s) of readline buffering?

Subject: Re: [BUGS] Nested xmlagg doesn't give a result 9.2.3
Exceeding length 4679 is a problem. Query results(length) equal or below this
number succeed.

When there are more then 88 rows in the table like 595 I can run the query with
success when using: WHERE id BETWEEN 1 AND 88;
Using LIMIT 88 fails -> returns nothingSelecting all fails as well.

When there are in __table_to_table more than 88 rows nothing gets returned,
otherwise the query rolls out fine.

It appears to be a Windows issue only.I'll try to post some code.

Seems your testing from different environments like that could easily add any
mix of libpq client libraries into the equation (??)
(Are both test machines running the same version of pgAdmin? and are both
connecting using the libpq installed with them?)
We have plenty of experience with clients reporting varying behavior from our
'applications', when it turns out they've 'hooked into' an unexpected version
of the libpq client without, for example, SSL support built in, or Kerberos,
or... This often happens after the client has unwittingly modified his
environment in some way, sometimes after installing software.
While the 'support libraries' issues above have no bearing on your case, of
course, I certainly don't know enough to know that the different versions of
libpq don't present xmlagg output differently!
The experts here will weigh in.

I mean when I'm physically behind the machine and login via pgadmin using
localhost or 192.168.1.100 then I get results.When I'm on another machine and
login via pgadmin(192.168.1.100) then I get no results.Not sure what to think
of this...

Yes, with 1 table only. I'm not getting any results.When I'm on the sql machine
via localhost or 192.168.1.100 I'm getting results.

Also no result with FROM __my_table LIMIT 1;I'm having correct results with PG

For example:

xmlelement
----------------------
<el_name>1</el_name>
Or:
postgres=# SELECT xmlagg(xmlelement(name el_name, id)) FROM __table;
xmlagg
------------------------------------------
<el_name>1</el_name><el_name>2</el_name>
(1 row)
Btw, such simple tests would have failed on the buildfarm for regression
xml.sql, so this looks to be an error in your environment.
Don't you have for example problems with the client application you use?
