No, you are NOT understanding correctly.
Restoring a table from pg_dump generally involves _ONE_ command.
For instance, the following is what pg_dump generates for my table, "stocks."
COPY stocks (symbol, description, exchange) FROM stdin;
AADBX AADBX NYSE
AADEX AADEX NYSE
AAIEX AAIEX NYSE
BTS.A BTS.A TSX
CTSTK TD Canadian Equity CTE
CASH CASH TSX
CTAMER TD AmeriGrowth RSP CTE
CTASIA TD AsiaGrowth RSP CTE
CTEMER TD Emerging Markets RSP CTE
CTEURO TD European Growth RSP CTE
CTIBND TD Global RSP Bond CTE
FDIVX FDIVX NYSE
FDRXX FDRXX NYSE
FUSEX FUSEX NYSE
MOT MOT NYSE
NCX NOVA Chemicals Corporation TSX

Recovery from this involves the SQL processor using ONE transaction
ID, and ONE SQL statement. If there were 8 billion rows in the table,
whatever other challenges there might be, it would still use ONE
transaction ID and ONE SQL statement.
What is there about "This involves just one SQL statement" that isn't
making sense?
