The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/14/functions-string.html Description:
In the new documentation https://www.postgresql.org/docs/14/functions-string.html you again lost information about ^@ operator for text and keep information about only function starts_with on which this operator is based. But ^@ is very important, because it can be accelerated by special index SP-GIST index. https://www.postgresql.org/docs/14/spgist-builtin-opclasses.html The task to filter text strings by prefix is rather common and using ^@ and SP-GIST is the best solution for this (rather options is to use starts_with without index acceleration or use LIKE construction with SP-GIST, which more complex (need to mention C locales), overengeniered and may be more slow). As I say the filtering text by prefix is very common task, but information about the best method is absent now.
