Fixed issue 2093 where pfree() was called with a NULL pointer. The issue is due to some confusion with pfree(). There are 2 definitions for it, one that checks for a passed NULL and the other which does not. Created a function, pfree_if_not_null(), to check for NULL and call pfree() if a NULL wasn't passed. Modified the pfree references in the following files - src/backend/commands/label_commands.c src/backend/executor/cypher_merge.c src/backend/executor/cypher_set.c src/backend/executor/cypher_utils.c src/backend/parser/ag_scanner.l src/backend/parser/cypher_analyze.c src/backend/parser/cypher_expr.c src/backend/parser/cypher_gram.y src/backend/parser/cypher_parse_agg.c src/backend/utils/adt/age_global_graph.c src/backend/utils/adt/age_graphid_ds.c src/backend/utils/adt/age_session_info.c src/backend/utils/adt/age_vle.c src/backend/utils/adt/agtype.c src/backend/utils/adt/agtype_gin.c src/backend/utils/adt/agtype_raw.c src/backend/utils/adt/agtype_util.c src/backend/utils/load/ag_load_edges.c src/backend/utils/load/ag_load_labels.c src/include/utils/age_graphid_ds.h src/include/utils/age_session_info.h src/include/utils/agtype.h Added regression tests for the original issue.
