We have a patch for pg_dump which adds a possibility to dump
a part of table, for example:
dump Top.Science.Astronomy heirarchy from dmoz catalog
pg_dump -d -t dmoz -w "select * from dmoz where path <@ 'Top.Science.Astronomy'" dmoz
We found it's very useful. We'd like to extend it to use also with COPY
but it has no support for select (of course it will works only for
special case when ALL columns retrieved).
The question is: Is't worth to submit patch for pg_dump and look into
copy code ?
Regards, Oleg
