How to amend Aurora Postgres' parameter `babelfishpg_tsql.escape_hatch_rowversion` value from `strict` to `ignore`

Hi.

TL;DR: I'm trying to understand how to change the parameter babelfishpg_tsql.escape_hatch_rowversion values to ignore for all SQL sessions ran against the TDS port.

I'm using Aurora Postgres and would like to create a table with a column of type timestamp. By default, the parameter babelfishpg_tsql.escape_hatch_rowversion defined in the Babelfish Postgres extension babelfishpg_tsql is set to strict, thus running a script to create a table with a column of type timestamp against the TDS port returns an error like the following: error : To use the TIMESTAMP datatype, set 'babelfishpg_tsql.escape_hatch_rowversion' to 'ignore'.

Example of a Create Table script:

CREATE TABLE schema1.tablename1 (
  column1 timestamp NOT NULL,
)

I can change the parameter value against the Postgres port using the command SET babelfishpg_tsql.escape_hatch_rowversion TO 'ignore';, and against the TDS port using the command sp_babelfish_configure 'babelfishpg_tsql.escape_hatch_rowversion', 'ignore'.

When running the command sp_babelfish_configure 'babelfishpg_tsql.escape_hatch_rowversion', 'ignore' against the TDS port in SQL Server Management Studio, I can run the above-mentioned create table command on the same SQL session successfully.

The parameter value change, though, is limited to a single session. I wanted to change the parameter value in a custom Aurora cluster parameter group created based on the default parameter group named aurora-postgresql15, but the parameter did not exist in the parameter group.
