Assuming pgAdmin is using  pg_stat_database then:

http://www.postgresql.org/docs/9.2/static/storage-file-layout.html

"Temporary files (for operations such as sorting more data than can fit
in memory) are created within PGDATA/base/pgsql_tmp, or within a
pgsql_tmp subdirectory of a tablespace directory if a tablespace other
than pg_default is specified for them. The name of a temporary file has
the form pgsql_tmpPPP.NNN, where PPP is the PID of the owning backend
and NNN distinguishes different temporary files of that backend."
