The slowdown is nowhere in the script - it's caused waiting for a return
from the call pg_exec $cn "commit". The table contains about 400K rows,
typically with about 10 columns (this varies, as the nature of the import
application is dynamic).

pgTcl package appears to be 1.5 (assuming the package folder pgtcl1.5 refers
to v1.5).

The import program imports a "flattened" import file and normalises the
columns to our enterprise database. All calls to pg_tcl functions are
wrapped with custom tcl procs we wrote to put a layer of abstraction between
the code and the sql calls. In fact, these wrap-around procs can swtich from
pgtcl calls to spi calls so that procs can be re-used in pg server-side TCL
SP''s. Included in these wrap-around functions is the ability to call
logging functions which write to log files, telling me the execution taime
and "explains" for every SQL call, if need be.

If the slowdowns were within TCL code, I would expect Ctrl-C to abort the
script, but in fact that app is unresponsive to Ctrl-C when the process
stalls.

PG version is Windows 8.1.2
