Thanks for looking into all the same.
if ( V_DBLINK_CONNECTION_NAMES is null or V_DBLINK_CONNECTION_NAME != any(V_DBLINK_CONNECTION_NAMES)I don't think you want "!=ANY" there. Shouldn't that be "<>ALL" ? "<>ANY" will *always* be true if there are at least two different entries.
In my simple test it works as expected with respect to that. But I did use it the wrong way as I thought that ! would invert the result of the any operation as a whole. I changed it to != all but the error persists.
The other thing is that you seem to call "dblink_get_result" on any existing connection before use. But you can only call the function if there is a result outstanding.
I call dblink_get_result only if I do not open a dblink connection, i. e. only on second and following function calls. I put more notice output into the code showing that dblink_send_query has been called once before the first call of dblink_get_result. I changed my query to reflect return bigint value of the called function write_message_to_table. Error persists.
I put a new pastebin https://pastebin.com/7R45R7qK and committed the changes.
