Hi
I have the following issue:
I have a development database that is altered a lot and a set of functions
that make use of dblink_build_sql_*.
The problem is that after I update a table whenever I use a function that
makes use of dblink_build_sql the server crashes.
The ALTER TABLE sequences usually add columns and do not drop any.
This does not happen on every table, just now and then.
This is what I get when running dblink_build_sql_update on a table
(channelstable). I must mention that all id's exist in the table... except for
id=2 that does not exist and dblink reports it as inexistent.
I must say that this happens on more than one table.
All tables have a single field primary key.
The alter table sequence does not affect the primary key.
Any ideas?...
Thanks in advance.
Command log follows:

q := q || dblink_build_sql_update('ChannelsTable', '1', 1,
ARRAY[i.pkey::TEXT], ARRAY[i.pkey::TEXT]);

server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
