  Trace, of course, doesn't try to expand value set at the "database" section using

the aliases.conf\databases.conf. Documentation at the beginning of the default

fbtrace.conf say:

# Pattern is either database name without path or "SIMILAR TO"-based regular
# expression which is matched against fully qualified database path name.
