Where, if anywhere, is the current documentation for writing or using a logical decoding output plugin consumer thingy?
I'm trying to find my way into it ... src/backend/replication/logical/logical.c, which textually contains most of the functions that appear to interact with the test_decoding module, contains this in the header comment: """ The idea is that a consumer provides three callbacks, one to read WAL, one to prepare a data write, and a final one for actually writing since their implementation depends on the type of consumer. Check logicalfunc.c for an example implementations of a fairly simple consumer and a implementation of a WAL reading callback that's suitable for simpler consumers. """ There is no file logicalfunc.c. And test_decoding actually uses five callbacks, not three. Is a consumer the same as a decoder? test_decoding.c contains this: /* These must be available to pg_dlsym() */ static void pg_decode_startup(LogicalDecodingContext *ctx, OutputPluginOptions *opt, bool is_init); ... which is surely wrong. -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
