76834: sql: execute batch statements in an implicit transaction r=otan a=rafiss fixes #44803 relates to #76490 Release justification: high value bug fix to existing functionality ### *: prepare tests for batch stmt txn change This commit will make the next one easier to review. ### sql: execute batch statements in an implicit transaction Release note (bug fix): Previously statements that arrived in a batch during the simple query protocol would all execute in their own implicit transactions. Now, we match the Postgres wire protocol, so all these statements share the same implicit transaction. If a BEGIN is included in a statement batch, then the existing implicit transaction is upgraded to an explicit transaction. ### sql: add session var for old implicit txn behavior Release note (sql change): The enable_implicit_transaction_for_batch_statements session variable was added. It defaults to true. When it is true, multiple statements in a single query (a.k.a. a "batch statement") will all be run in the same implicit transaction, which matches the Postgres wire protocol.

This commit will make the next one easier to review. Release justification: test only change Release note: None
Release justification: high value bug fix to existing functionality. Release note (bug fix): Previously statements that arrived in a batch during the simple query protocol would all execute in their own implicit transactions. Now, we match the Postgres wire protocol, so all these statements share the same implicit transaction. If a BEGIN is included in a statement batch, then the existing implicit transaction is upgraded to an explicit transaction.
Release justification: low risk new setting. Release note (sql change): The enable_implicit_transaction_for_batch_statements session variable was added. It defaults to true. When it is true, multiple statements in a single query (a.k.a. a "batch statement") will all be run in the same implicit transaction, which matches the Postgres wire protocol. This setting is provided for users who want to preserve the behavior of CockroachDB versions v21.2 and earlier.

sql: execute batch statements in an implicit transaction
Release note (bug fix): Previously statements that arrived in a batch
during the simple query protocol would all execute in their own implicit
transactions. Now, we match the Postgres wire protocol, so all these
statements share the same implicit transaction. If a BEGIN is included
in a statement batch, then the existing implicit transaction is
upgraded to an explicit transaction.
sql: add session var for old implicit txn behavior
Release note (sql change): The enable_implicit_transaction_for_batch_statements
session variable was added. It defaults to true. When it is true,
multiple statements in a single query (a.k.a. a "batch statement") will
all be run in the same implicit transaction, which matches the Postgres
wire protocol. This setting is provided for users who want to preserve
the behavior of CockroachDB versions v21.2 and earlier.
