I am quite thorough and keep database access restricted to a single
class with strict exception handling to catch errors. And force the
connection to close / force disposal everywhere. But I shall certainly
be checking my code - thanks for the tip.

Interesting what Francis says about the pool connections being closed
before disposal. Presumably I should never get this error if I use Npgsql?
