If you've defined a parse_trace_flag() method in ::db you'll also want
it in ::st, so just alias it in:

  *parse_trace_flag = \&DBD::foo:db::parse_trace_flag;

You may want to act on the current 'SQL' trace flag that DBI defines
to output SQL prepared/executed as DBI currently does not do SQL
tracing.

=head2 Trace Macros

Access to the trace level and trace flags is via a set of macros.

  DBIc_TRACE_SETTINGS(imp) returns the trace settings
  DBIc_TRACE_LEVEL(imp) returns the trace level
  DBIc_TRACE_FLAGS(imp) returns the trace flags
  DBIc_TRACE(imp, flags, flaglevel, level)

  e.g.,
