Hi, I'm considering changing my database schema upgrade routines to recreate functions and all objects depending on them (e.g. triggers, views) just after the database server is started. It would make the routines much simpler since they wouldn't have to depend on the history of the schema. Does anyone has any experience with recreating all functions and triggers to upgrade a database schema assuming that during the upgrade there are no client connections to the database? Does anyone see any problems with such approach in terms of consistency and performance? I'm not familiar with PostgreSQL internals and I'm not sure how it would affect the planner when using various function volatile categories.
Do you have indexes that use those functions? It would help to just give an example of your situation and what you are trying to solve. Why recreate triggers, indexes and functions after server startup instead of leaving them? Why create needless traffic?
