Обсуждение: pgsql: Read include/exclude commands for dump/restore from file
Read include/exclude commands for dump/restore from file
When there is a need to filter multiple tables with include and/or exclude
options it's quite possible to run into the limitations of the commandline.
This adds a --filter=FILENAME feature to pg_dump, pg_dumpall and pg_restore
which is used to supply a file containing object exclude/include commands
which work just like their commandline counterparts. The format of the file
is one command per row like:
<command> <object> <objectpattern>
<command> can be "include" or "exclude", <object> can be table_data, index
table_data_and_children, database, extension, foreign_data, function, table
schema, table_and_children or trigger.
This patch has gone through many revisions and design changes over a long
period of time, the list of reviewers reflect reviewers of some version of
the patch, not necessarily the final version.
Patch by Pavel Stehule with some additional hacking by me.
