Replace hardcoded WithGlobalLock assignment with configurable
options wallet postgres backends. Also add the WithGlobalLock
option to the channeldb table for postgres backends.
Defaults:
- channeldb: false (allow concurrent access)
- wallet: true (maintain safe single-writer behavior)
Users can now override these defaults via:
- db.postgres.channeldb-with-global-lock
- db.postgres.walletdb-with-global-lock
This gives operators flexibility while maintaining safe defaults
until full native SQL migration is complete.
Moreover exclude db.postgres.walletdb-with-global-lock check
in the sample config file script. We cannot easily check the
correct default because we set it later in the LND startup
sequence so we exclude it.
Because we need to remain backwards compatible with the old
`dust-threshold` value we set the default value for
`channel-max-fee-exposure` later in the program flow. Given
the restrictions of the sample config check we need to exclude
this value from the check.
The new script perfoms the following checks on the sample-lnd.conf file:
1. Checks that all relevant options of lnd are included.
2. Verifies that defaults are labeled if there are also further examples.
3. Checks that all default values of lnd --help are mentioned correctly,
including empty defaults and booleans which are set to false by
default.
