Hello,
I've written a perl script that uses DBD::Pg func calls to do COPY FROM
STDIN. It does several copies as a single transaction. While this works
fine on my Linux box with Posgresql 7.4.2, it seems to hang while
finishing up the last copy or closing the transaction on my Mac (also
7.4.2). By 'hang', I mean that the postgres process runs on
indefinitely consuming 90% of the cpu. The setups are similar; I've
done similar tuning to both databases (though, admittedly, I don't know
as much about doing this for a Mac). Generally, Postgresql is a little
slower on the Mac, but I haven't had any real problems with it.
Any ideas? The script is copied below, and the part that does the copy
and commit is at the bottom.
Thanks much,
Scott

=head1 NAME
gmod_bulk_load.pl - Bulk loads gff3 files into a chado database.
=head1 SYNOPSIS %
gmod_bulk_load.pl
=head1 COMMAND-LINE OPTIONS
--gfffile The file containing GFF3 (optional, can read from stdin)--organism The organism for the
data--dbname Database name--dbuser Database user name--dbpass Database password--dbhost Database
host--dbport Database port
Note that all of the arguments that begin 'db' can be provided by default
by Bio::GMOD::Config, which was installed when 'make install' was run.
=head1 DESCRIPTION
=head2 NOTES
=over
=item The ORGANISM table
This script assumes that the organism table is populated with information
about your organism. If you are unsure if that is the case, you can
execute this command from the psql command-line:
select * from organism;
If you do not see your organism listed, execute this command to insert it:
insert into organism (abbreviation, genus, species, common_name)
values ('H.sapiens', 'Homo','sapiens','Human');
substituting in the appropriate values for your organism.
=item GFF3
The GFF in the datafile must be version 3 due to its tighter control of
the specification and use of controlled vocabulary. Accordingly, the names
of feature types must be exactly those in the Sequence Ontology, not the
synonyms and not the accession numbers (SO accession numbers may be
supported in future versions of this script). There are several caveates
about the GFF3 that will work with this bulk loader:
=over
=item Reference sequences
This loader requires that the reference sequence features be already
loaded into the database (for instance, by using gmod_load_gff3.pl).
Future versions of this bulk loader will not have this restriction.
=item Parents/children order
Parents must come before children in the GFF file.
=item Several GFF tags (both reserved and custom) not supported
These include:
=over
=item Dbxref
=item Target
=item Gap
=item Any custom (ie, lowercase-first) tag
=back
=item No sequences
This loader does not load DNA sequences, though chromosome sequences
can be loaded with gmod_load_gff3 when the reference sequence features
are loaded.
