I have no idea where this comes from - I've grepped globally for that
silly string and can't find it. The installation is pretty standard -
pg+plsql. Must be something deep which I've forgotten about.
The problem was this: a silly SQL error (misuse of OR and missing
parentheses) resulted in a massive result set which resulted in OOM - if
the select is run manually (no funny "out of balance" strings).
If it's run in a function (which uses a FOR loop, which uses implicit
cursors), then the "out of balance" string is returned for the TEXT column
almost immediately.
Weird. Anyway, I'm just relieved the solution was fixing my stupid SQL.
