We used to parse qualified table names as a simple string, which then
breaks attempts to be smart about how to quote idenfifiers. Some sources
are known to accept dots in quoted table names and we need to be able to
process that properly without tripping on qualified table names too
late.
Current code might not be the best approach as it's just using either a
cons or a string for table names internally, rather than defining a
proper data structure with a schema and a name slot.
Well, that's for a later cleanup patch, I happen to be lazy tonight.
This option is dangerous and allows to skip ALL triggers when loading
data against PostgreSQL. This includes foreign key constraints
definitions and will allow loading data out of order.
When using both the options "create no table" and "disable triggers" it
will be possible to load data into a schema prepared by your favorite
external tool, at the cost of not validating FK constraints. Use with
care.
Fix#167.
In passing also allow --field to specify the whole field list, there's
no point in forcing the user to have as many --field switches on the
command line as they have columns in their data source file.
That's the big refactoring patch I've been sitting on for too long.
First, refactor connection handling to use a uniformed "connection"
concept (class and generic functions API) everywhere, so that the COPY
derived objects just use that in their :source-db and :target-db slots.
Given that, we don't need no messing around with *pgconn* and *myconn-*
and other special variables at all anywhere in the tree.
Second, clean up some oddities accumulated over time, where some parts
of the code didn't get the memo when new API got into place.
Third, fix any other oddity or missing part found while doing those
first two activities, it was long overdue anyway...
Make it so that the following command line usages are accepted when
using pgloader without a command file:
./build/bin/pgloader ./test/sqlite/sqlite.db postgresql:///pgloader
./build/bin/pgloader --set "search_path='sakila'" \
mysql://root@localhost/sakila \
postgresql:///sakila
./build/bin/pgloader --type csv \
--field id --field field \
--with truncate \
--with "fields terminated by ','" \
./test/data/matching-1.csv \
postgres:///pgloader?matching
It's now possible in most cases to just use command-line options, which
should make the entry bar to pgloader much lower.
