Which sequences are associated with the PK for PLUGIN_SETTING and CWD_USER_ATTRIBUTE?

[Sue Bridges]

6.7.2 install of BitBucket with our old BitBucket data (4.7.2). 

atlassian_bitbucket.log contains Oracle errors - possibly to do with sequences?

CWD_USER_ATTRIBUTE table

ORA-00001: unique constraint (STASH.SYS_PK_10202) violated

PLUGIN_SETTING table

ORA-00001: unique constraint (STASH.PK_PLUGIN_SETTING) violated

Apart from a couple of the sequences, this would make sense as they are all set to 1.

Whereas good practice would be to call the sequence something similar to the table_name, in this case, the names of the sequences are not very helpful to indicate which sequence I need to change.

Thanks in advance.
