I have successfully configured Bucardo to replicate a database. But I
have run into problems adding a second database, namely because I have a
table that shares a name in both databases. And I don't know how to get
"bucardo add herd" to specify which database I want. This is under
Ubuntu 14 (64 bit), Postgres 9.3.13, and Bucardo 5.4.1.
Specifics:
Config for the first database
bucardo list databases
Database: msl_devu14_64 Status: active Conn: psql -U bucardo -d msl
Database: msl_sysmsl Status: active Conn: psql -U bucardo -d msl
bucardo list tables
25. Table: public.center_split_parms DB: msl_sysmsl PK: state|county
(integer|int4)
26. Table: public.county DB: msl_sysmsl PK: rid (integer)
27. Table: public.grid DB: msl_sysmsl PK:
rid|county|state (integer|int4|int4)
28. Table: public.parcel DB: msl_sysmsl PK: rid (integer)
29. Table: public.parcel_name DB: msl_sysmsl PK: rid|seq
(integer|int4)
30. Table: public.place DB: msl_sysmsl PK: rid (integer)
31. Table: public.rule_zone DB: msl_sysmsl PK: state_no|id
(integer|int4)
32. Table: public.state DB: msl_sysmsl PK: state (integer)
33. Table: public.street DB: msl_sysmsl PK: rid (integer)
34. Table: public.update_time DB: msl_sysmsl PK:
state|county|tbl_name (integer|int4|text)
bucardo list sequences
Sequence: public.id_seq DB: msl_sysmsl
bucardo list herds
Relgroup: msl_herd DB: msl_sysmsl Members: public.center_split_parms,
public.county, public.grid, public.id_seq, public.parcel,
public.parcel_name, public.place, public.rule_zone, public.state,
public.street, public.update_time
Used in syncs: msl_sync
bucardo list syncs
Sync "msl_sync" Relgroup "msl_herd" [Active]
DB group "msl_sync" msl_devu14_64:target msl_sysmsl:source
I then added my next database, tables, and sequences:
bucardo add database stringsDB_sysmsl dbname=stringsDB
bucardo add table db=stringsDB_sysmsl public.district public.names
public.place
bucardo add sequence db=stringsDB_sysmsl public.name_id public.district_id
As you can see from my table list, I now have 2 tables named place
bucardo list tables place
30. Table: public.place DB: msl_sysmsl PK: rid (integer)
38. Table: public.place DB: stringsDB_sysmsl PK: id (integer)
If I try to create my herd, it is always taking the the lower ID'd
table, which fails because it spans 2 databases:
bucardo add herd stringsDB_herd public.district public.names
public.place public.name_id public.district_id
Created relgroup "stringsDB_herd"
DBD::Pg::st execute failed: ERROR: Cannot have relations from different
databases in the same relgroup (5) at line 17.
CONTEXT: PL/Perl function "herdcheck" at /usr/local/bin/bucardo line 4092.
Any thoughts here? I don't see anything on the wiki dealing with this
error or how to be more specific than public.place. I've tried pretty
much everything I could think of
bucardo add herd stringsDB_herd public.district public.names
stringsDB_sysmsl.public.place public.name_id public.district_id
Created relgroup "stringsDB_herd"
Did not find matches for the following terms:
stringsDB_sysmsl.public.place
The following tables or sequences are now part of the relgroup
"stringsDB_herd":
public.district
public.district_id
public.name_id
public.names
stringsDB_sysmsl:public.place
public.place:stringsDB_sysmsl
public.place,stringsDB_sysmsl
Here are all the various combinations I have tried:
stringsDB_sysmsl.public.place
stringsDB_sysmsl:public.place
public.place:stringsDB_sysmsl
public.place,stringsDB_sysmsl
stringsDB.public.place
stringsDB:public.place
stringsDB,public.place
I also tried
bucardo add herd stringsDB_herd dbname=stringsDB public.district
public.names public.place public.name_id public.district_id
and
bucardo add herd stringsDB_herd dbname=stringsDB_sysmsl public.district
public.names public.place public.name_id public.district_id
I am pretty much at a loss. TIA!
