◆ veil_share()

Datum veil_share ( PG_FUNCTION_ARGS )

veil_share(name text) returns bool Define a shared variable called NAME, returning true.

If the variable is already defined as a session variable an ERROR will be raised.

Session variables are simply defined by their first usage. Shared variables must be defined using this function. They may then be used in exactly the same way as session variables. Shared variables are shared by all backends and so need only be initialised once. The result of this function tells the caller whether the variable needs to be initialised. The caller that first defines a shared variable will get a false result and from this will know that the variable must be initialised. All subsequent callers will get a true result and so will know that the variable is already initialised.

Parameters

fcinfo name text name of variable.

Returns: bool true if the variable already exists

This creates a new shared memory context with none of the existing shared variables. All current transactions will be able to continue using the current variables, all new transactions will see the new set, once this function has completed.

Parameters

fcinfo

Returns: bool True if the function is able to complete successfully. If it is unable, no harm will have been done but neither will a memory reset have been performed.

This function will always reset the shared memory context, even for sessions that are still using it. Having taken this drastic action, it will then cause a panic to reset the server.

Question - won't a panic reset the shared memory in any case? Is the panic superfluous, or maybe is this entire function superfluous?
