Hi,
When I read the documents and coding of SPI, [1]
I found that the following the SPI_start_transaction does not support
transaciton_mode(ISOLATION LEVEL, READ WRITE/READ ONLY) like BEGIN
command. [2]
Is there a reason for this?
Per the documentation for SPI_start_transaction that you linked to:
"SPI_start_transaction does nothing, and exists only for code
compatibility with earlier PostgreSQL releases."
I haven't tested it, but perhaps you can do "SET TRANSACTION ISOLATION
LEVEL" in the new transaction after calling SPI_commit() though. Or "SET
DEFAULT TRANSACTION ISOLATION LEVEL" before committing.
