gudusoft.gsqlparser.ir.builder.postgresql.PostgresqlRoutineRefResolver

public final class PostgresqlRoutineRefResolver
extends AbstractRoutineRefResolver

PostgreSQL routine reference resolver with search_path support.

Resolution tiers:

1. Exact schema.name match
2. Walk search_path for unqualified names
3. Same-schema preference for intra-file calls
4. pg_catalog always implicit last in search_path
5. Ambiguity when multiple search-path matches with equal strength

tryResolve

protected BoundRoutineRef tryResolve(BoundRoutineRef ref,
                                     BoundProgram program,
                                     Map<String,BoundRoutineSymbol> upperIndex,
                                     Map<String,List<BoundRoutineSymbol>> nameIndex)

Description copied from class: AbstractRoutineRefResolver

Attempts to resolve a single routine ref against the known routines.

Specified by:

tryResolve in class AbstractRoutineRefResolver

Parameters:

ref - the unresolved ref

program - the program containing all routines

upperIndex - case-insensitive routineId → symbol index

nameIndex - case-insensitive name → list of symbols index

Returns:

resolved ref, or null if no match found

classifyExternalIfKnown

protected void classifyExternalIfKnown(BoundRoutineRef ref)

Description copied from class: AbstractRoutineRefResolver

Called for unresolved refs to check if they are known external dependencies. Subclasses should set properties like "externalDependency", "externalType", etc.
