What data format does copy_data_from expect?
jimfulton opened this issue · comments
I tried referencing a tablespace directory containing a single database and that failed:
>>> pg = testing.postgresql.Postgresql(copy_data_from='/aledade-test-data')
pg = testing.postgresql.Postgresql(copy_data_from='/aledade-test-data')
Traceback (most recent call last):
File "<console>", line 1, in <module>

testing.postgresql
expects a directory that is generated by initdb
command:
$ initdb -D example -U postgres
$ ls example/
PG_VERSION global/ pg_hba.conf pg_multixact/ pg_subtrans/ pg_twophase/ postgresql.conf
base/ pg_clog/ pg_ident.conf pg_stat_tmp/ pg_tblspc/ pg_xlog/
$ python
>>> import testing.postgresql
>>> pg = testing.postgresql.Postgresql(copy_data_from='example')
>>> pg.stop()
Thanks.
should prolly go into the readme.
