[Regression] target.account has been changed to replace underscores with dashes

[mbdataminr]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

When upgrading from dbt 1.8 to 1.9
{{ target.account }} is now replaces underscores with dashes. For example, if the target.account is set to sample_company, then the compiled code now generates sample-company.

If logic is based on this (eg, {% if target.account|lower == 'sample_account' %}), this change breaks existing code. This was not outlined in the release notes for upgrading dbt versions.

Expected Behavior

Expected that target.account would be compared to what is in the profiles.yml, not modified.

Steps To Reproduce

1. Set account to a value with underscores (sample_company)
2. Create a model with the code, eg:
   select '{{ target.account }}'
3. Run model on versions 1.8 vs 1.9. 1.9 replaces target.account underscores with dashes.

Thanks for reporting this @mbdataminr ! I'm going to transfer this to dbt-snowflake for further follow-up by another member of our team.

In the meantime, this appears related to dbt-labs/dbt-snowflake#1068 / dbt-labs/dbt-snowflake#1067 which is related to an issue related to the Snowflake Python driver for Python 3.11+.

Reading through the information in the links above, it looks like our preferred resolution would have been if the fix was within the Snowflake Python connector: snowflakedb/snowflake-connector-python#1839 (comment).

I'm sorry that this change breaks your existing code. I've opened dbt-labs/docs.getdbt.com#6759 to add a note about this change in the release notes and/or upgrade guide for v1.9.
