/*
|
|
* Cache subsystem. Molecules and fingerprints I/O is extremely expensive.
|
|
*
|
|
* This module provides support for caching the toasted data values that
|
|
* functions receive as argument, together with their detoasted,
|
|
* deserialized, or signature representations. This may help saving the time
|
|
* that would be otherwise required to some queries to process the same
|
|
* argument values multiple times (for example repeatedly unpickling the
|
|
* same RDKit molecule).
|
|
*
|
|
* This cache mechanism also provides the functions code with a high level
|
|
* API that encapsulates the details of the conversion from the toasted
|
|
* PostgreSQL Datum and the different representations of the supported
|
|
* value types.
|
|
*
|
|
* A cache instance is associated with a memory context where the
|
|
* cached values are allocated, and it's therefore automatically cleared
|
|
* when the same context is reset or destroyed. For this reason the client
|
|
* code doesn't usually create/use this cache with the "current" memory
|
|
* context, but rather with the longer-living context that is available
|
|
* to the function as fcinfo->flinfo->fn_mcxt.
